Man builds metal helicopter in Malawi
45-year-old man builds an ho
memade helicopter in Malawi, which has never taken off from the ground but it has attracted a lot of crowd.
Felix Kambwiri standing beside his self-made helicopter
The man, who was identified as Felix Kambwiri, has spent the last four months constructing his dream machine out of scrap metal and fibre-glass in his garage in the village of Gobede, 90km north of the capital Lilongwe.
Clambering inside the one-seater cockpit, he swings the door closed, turns the key, pumps the pedals, and the 125-cc secondhand engine roars into life as orange lights flash impressively. Speaking on his achievement:
Kambwiri said: “I would like just to fly for even five minutes to show that I am serious about this and that it is not a joke. This helicopter can fly. Every day I receive many curious visitors who have heard about me. Police regularly come here to monitor progress and make sure I don’t fly without permission. I can understand their concern is about my safety, and that of people who might come in their hundreds on the day I fly the helicopter. I will not take risks. I will wait until I am ready. I cannot allow anyone to take the risk for fear of an accident.”
Kambwiri built the helicopter to his own design after failing to find any books to help fulfil his life’s passion.
But he has been warned that he should not undertake any test flights until the civil aviation authorities have completed safety checks.
Nice innovation!

HTML stands for Hyper Text Markup Language HTML is not a programming language, it is a markup language A markup language is a set of markup tags HTML uses markup tags to describe web pages HTML Tags HTML markup tags are usually called HTML tags HTML tags are keywords surrounded by angle brackets like HTML tags normally come in pairs like and The first tag in a pair is the start tag, the second tag is the end tag Start and end tags are also called opening tags and closing tags. HTML Documents - Web Pages HTML documents describe web pages HTML documents contain HTML tags and plain text HTML documents are also called web pages The purpose of a web browsers (like Internet Explorer) is to read HTML documents and display them as web pages. The browser does not display the HTML tags, but uses the tags to interpret the content of the page:My First Heading

HTML Colors
Colors are displayed combining RED, GREEN, and BLUE light. Color Values HTML colors are defined using a hexadecimal (hex) notation for the combination of Red, Green, and Blue color values (RGB). The lowest value that can be given to one of the light sources is 0 (hex 00). The highest value is 255 (hex FF). Hex values are written as 3 double digit numbers, starting with a # sign. Color Color HEX Color RGB #000000 rgb(0,0,0) #FF0000 rgb(255,0,0) #00FF00 rgb(0,255,0) #0000FF rgb(0,0,255) #FFFF00 rgb(255,255,0) #00FFFF rgb(0,255,255) #FF00FF rgb(255,0,255) #C0C0C0 rgb(192,192,192) #FFFFFF rgb(255,255,255) 16 Million Different Colors The combination of Red, Green and Blue values from 0 to 255 gives a total of more than 16 million different colors to play with (256 x 256 x 256). Most modern monitors are capable of displaying at least 16384 different colors. If you look at the color table below, you will see the result of varying the red light from 0 to 255, while keeping the green and blue light at zero. To see a full list of color mixes when the red light varies from 0 to 255, click on one of the hex or rgb values below.

If you want to use other colors, you should specify their HEX value. Web Safe Colors? Some years ago, when computers supported max 256 different colors, a list of 216 "Web Safe Colors" was suggested as a Web standard, reserving 40 fixed system colors. The 216 cross-browser color palette was created to ensure that all computers would display the colors correctly when running a 256 color palette. This is not important now, since most computers can display millions of different colors. Anyway here is the list: 000000 000033 000066 000099 0000CC 0000FF 003300 003333 003366 003399 0033CC 0033FF 006600 006633 006666 006699 0066CC 0066FF 009900 009933 009966 009999 0099CC 0099FF 00CC00 00CC33 00CC66 00CC99 00CCCC 00CCFF 00FF00 00FF33 00FF66 00FF99 00FFCC 00FFFF 330000 330033 330066 330099 3300CC 3300FF 333300 333333 333366 333399 3333CC 3333FF 336600 336633 336666 336699 3366CC 3366FF 339900 339933 339966 339999 3399CC 3399FF 33CC00 33CC33 33CC66 33CC99 33CCCC 33CCFF 33FF00 33FF33 33FF66 33FF99 33FFCC 33FFFF 660000 660033 660066 660099 6600CC 6600FF 663300 663333 663366 663399 6633CC 6633FF 666600 666633 666666 666699 6666CC 6666FF 669900 669933 669966 669999 6699CC 6699FF 66CC00 66CC33 66CC66 66CC99 66CCCC 66CCFF 66FF00 66FF33 66FF66 66FF99 66FFCC 66FFFF 990000 990033 990066 990099 9900CC 9900FF 993300 993333 993366 993399 9933CC 9933FF 996600 996633 996666 996699 9966CC 9966FF 999900 999933 999966 999999 9999CC 9999FF 99CC00 99CC33 99CC66 99CC99 99CCCC 99CCFF 99FF00 99FF33 99FF66 99FF99 99FFCC 99FFFF CC0000 CC0033 CC0066 CC0099 CC00CC CC00FF CC3300 CC3333 CC3366 CC3399 CC33CC CC33FF CC6600 CC6633 CC6666 CC6699 CC66CC CC66FF CC9900 CC9933 CC9966 CC9999 CC99CC CC99FF CCCC00 CCCC33 CCCC66 CCCC99 CCCCCC CCCCFF CCFF00 CCFF33 CCFF66 CCFF99 CCFFCC CCFFFF FF0000 FF0033 FF0066 FF0099 FF00CC FF00FF FF3300 FF3333 FF3366 FF3399 FF33CC FF33FF FF6600 FF6633 FF6666 FF6699 FF66CC FF66FF FF9900 FF9933 FF9966 FF9999 FF99CC FF99FF FFCC00 FFCC33 FFCC66 FFCC99 FFCCCC FFCCFF FFFF00 FFFF33 FFFF66 FFFF99 FFFFCC FFFFFF

HTML Elements
This is a paragraph
This is a link HTML Element Syntax An HTML element starts with a start tag An HTML element ends with an end tag The element content is everything between the start and end tag Some HTML elements have empty content Some HTML elements have a missing end tag Note: The start tag can have additional information (attributes). See next chapter. Nested HTML Elements Most HTML elements can be nested (can contain other HTML elements). Most HTML documents consist of nested HTML elements. HTML Document ExampleThis is my first paragraph
The example above contains 3 HTML elements:This is my first paragraph
Theelement defines a paragraph in the HTML document: The element has a start tag
and an end tag
The element content is: This is my first paragraphThis is my first paragraph
The element defines the body of the HTML document The element has a start tag and an end tag The element content is another element (a paragraph)This is my first paragraph
The element defines the whole HTML document. The element has a start tag and an end tag The element content is another element (the body) Empty HTML Elements HTML elements without content are called empty elements. Empty elements have no end tag.is an empty element without a closing tag. In XHTML, XML, and future versions of HTML, all elements must be closed. Adding a slash to the start tag, like
, is the proper way of closing empty elements, accepted by HTML, XHTML and XML. Even if
works in all browsers, writing
instead is more future proof. HTML Tip - Lowercase Tags HTML tags are not case sensitive:
means the same as
. Plenty of web sites use uppercase HTML tags in their pages. W3Schools use lowercase tags because the World Wide Web Consortium (W3C) recommends lowercase in HTML 4, and demands lowercase tags in newer versions of (X)HTML.

Note: Browsers automatically adds an empty line before and after paragraphs. Don't Forget the End Tag Most browsers will display HTML correctly even if you forget the end tag:This is a paragraph
This is another paragraph
The example above will work in most browsers, but don't rely on it. Forgetting the end tag can produce unexpected results or errors.
Note: Future version of HTML will not allow you to skip end tags.
HTML Line Breaks
Use the
tag if you want a line break (a new line) without starting a new paragraph:

. You can read more about empty HTML tags in the next chapters of this tutorial.
or
In XHTML, XML, and future versions of HTML, tags with no end tags (closing tags) are not allowed. Even if
works in all browsers, writing
instead is more future proof. HTML Rules (Lines) The
tag is used to create an horizontal rule (line). Example:

HTML Output - Useful Tips You cannot be sure how HTML will be displayed. Large or small screens, and resized windows will create different results. With HTML, you cannot change the output by adding extra spaces or extra lines in your HTML code. The browser will remove extra spaces and extra lines when the page is displayed. Any number of lines count as one space, and any number of spaces count as one space. HTML Tag Reference When you lookup W3Schools' tag reference, you will see additional information about tags and their attributes. You will learn more about HTML tag attributes in the next chapters of this tutorial. Tag Description

Note: Browsers automatically adds an empty line before and after headings. Headings Are Important Use the HTML heading tags for headings only. Don't use headings to make something BIG or bold. Search engines use your headings to index the structure and content of your web pages. Since users may skim your pages by its headings, it is important to use headings to show the document structure. H1 headings should be used as main headings, followed by H2 headings, and less important H3 headings, and so on. HTML Comments Comments can be inserted in the HTML code to make it more readable and understandable. Comments are ignored by the browser and not displayed.

HTML - Getting Started
What Do You Need? You don't need any tools to learn HTML at W3Schools. You don't need any HTML editor You don't need a web server You don't need a web site Editing HTML In this tutorial we use a plain text editor (like Notepad) to edit HTML. We believe this is the best way to learn HTML. However, professional web developers often prefer HTML editors like FrontPage or Dreamweaver, instead of writing plain text. Creating Your Own Test Web If you just want to learn HTML, skip the rest of this chapter. If you want to create a test web on your own computer, just copy the 3 files below to your desktop. (Right click on each link, and select "save target as" or "save link as") After you have copied the files, you can double-click on the file called "mainpage.htm" and see your first web site in action. Use Your Test Web For Learning We suggest you experiment with everything you learn at W3Schools by editing your web files with a text editor (like Notepad). Note: If your first web site contains HTML markup tags you have not learned yet, don't panic. You will learn much more HTML in the next chapters.
HTM or HTML Extension? When you save an HTML file, you can use either the .htm or the .html extension. We use .htm in our examples. It is a habit from the past, when the software only allowed three letters in file extensions. With new software it is perfectly safe to use .html.

Types of Mechanical Forces
A force exerted on a body can cause a change in either the shape or the motion of the body. The unit of force in SI system is the newton (N) and CGS system is dyne. No solid body is perfectly rigid and when forces are applied to it, changes in dimensions occur. Such changes are not always perceptible to the human eye since they are negligible. For example, the span of a bridge will sag under the weight of a vehicle and a spanner will bend slightly when tightening a nut. It is important for civil engineers and designers to appreciate the effects of forces on materials, together with their mechanical properties of materials. There are three main types of mechanical forces that can act on a body. They are:
1. Tensile force 2. Compressive force and 3. Shear force

Difference between the petrol engine and diesel engine
The temperature at the end of the compression
is less for the petrol engine.
Thus a spark plug is needed for the compression. In case of the diesel engine the temperature at the end of the compression is above the self-ignition temperature of the fuel.
Hence the fuel ignited is allowed to enter the
cylinder due to the high temperature.
No spark plug is required for the diesel
engine.
For the separate entry of the fuel after the compression stroke, a nozzle is provided for the diesel engines.
In case of the petrol engine they do not have
the nozzle.
In petrol engine the air and the fuel, are mix inside a carburetor before entering the engine cylinder. In diesel engine there is no mixing of air and fuel before suction stroke. Hence diesel engine does not have a carburetor.
Heat addition must take place at the constant volume for petrol engine. It takes place at the constant pressure for diesel engine
For the same compression ratio, the efficiency of a petrol engine is higher than that of the diesel engine. This is theoretical.
In an actual practice the compression ratio of a diesel engine is 1.5 times to 2 times more than that of a petrol engine.
Hence the diesel engine efficiency is much
higher.
Under some conditions the air fuel ratio for the petrol engine must be 16 and for the diesel engine case the ratio of the air fuel mixture must be 25 to 35.
Difference between 2 stroke and 4 stroke Engine
In the 2 stroke engine it consists of one cycle
with one rotation
In the 4 stroke engine it consists of one cycle
with two rotations.
The inlet and the exhaust valves of the 4 stroke engine are replaced by 3 ports in a 2 stroke engine.
In 2 stroke engine the lubrication oil must be
mixed with the petrol
In case of 4 stroke engine the lubrication and the fueling must take place separately
In the 2 stroke engine due to the presence of the lubrication oil, some of the lubrication oil must be combusted during the time of heat addition. Hence there is more friction and loss of work in 2 Engine
The power available in the 2 stroke engine is
only 70% of the calculated power
In 4 stroke engine the power available is 90%
of the calculated power
In 2 stroke engine the transfer port and the exhaust port are opened at the same time. Hence some fresh air fuel mixture will be escaped out of the engine cylinder, due to which there is loss of fuel.
For single cylinder engine the size of the flywheel is bigger than the 4 stroke engine.
Due to the above reason the 2 stroke engine on the roads are replaced by the 4 stroke engine
The overall efficiency of a 4 stroke engine is much higher than that of a 2 stroke engine.
What skills do mechanical engineers need?
The essence of engineering is problem solving. With this at its core, mechanical engineering also requires applied creativity — a hands on understanding of the work involved — along with strong interpersonal skills like networking, leadership, and conflict management. Creating a product is only part of the equation; knowing how to work with people, ideas, data, and economics fully makes a mechanical engineer.
What tasks do mechanical engineers do?
Careers in mechanical engineering call for a variety of tasks.
· Conceptual design · Analysis · Presentations and report writing · Multidisciplinary teamwork · Concurrent engineering
· Benchmarking the competition
· Measurements · Data Interpretation · Developmental design
· Research · Analysis (FEA and CFD)
· Working with suppliers
· Project management · Sales · Prototyping · Consulting · Testing · Customer service
Read tips for healthy life
1. Avoid fried eggplant
It soaks up oil quickly, like a sponge—more than
any other vegetable, even more than French fries.
Try grilling, broiling, baking, steaming, or braising
it instead of frying.
2. Follow these guidelines for cooking eggs
You need not cook eggs to the hard and rubbery
stage. Boiling an egg in its shell at 140° for 3H
minutes should kill virtually all bacteria.
Scrambled eggs and omelets are fine if cooked
just past the runny, moist stage (they should be
set, but don’t have to be rock hard). If you’re
frying eggs, “over easy” is best: fry them for
about 3 minutes on one side, then about 1 minute
on the other.
3. Eat sweet potatoes
Despite their sweet taste, they have about the
same number of calories per ounce as white
potatoes.
A 3 ounce baked sweet potato contains three
times the recommended daily amount of beta
carotene, half theRDA for vitamin C, and just 100
calories.
Avoid the typical package of ground poultry,
which usually contains skin and too much fat.
Look for ground turkey breast; it should be
labeled 96 to 98% fatfree (by weight).
4. Try veggie burgers
They’re served in many restaurants, and you’ll
find them in frozen, refrigerated, or mix form in
the grocery store. Veggie burgers may be
primarily soy and/or may contain any
combination of mushrooms, onions, peppers, rice,
oats, barley, bulgur (cracked wheat), rye, gluten
(wheat protein), beans, spices, and egg whites.
In a restaurant, ask the waiter what’s in the
veggie burger and how it’s cooked. Some veggie
burgers are almost fatfree, but some are high in
fat, especially if nuts or cheese are major
ingredients.
5. Eat beans and other legumes
Beans, lentils, and dried peas are all good
sources of soluble fiber, which, if consumed
regularly, may help lower blood cholesterol levels.
6. Cook with fresh herbs
They contain powerful antioxidant compounds,
according to a USDA analysis. Herbs that scored
highest by far were oregano and marjoram—just a
tablespoon or two of the chopped herbs would
supply significant amounts of antioxidants.
Fresh herbs are more potent (in flavor and
antioxidant power) than their dried counterparts,
and culinary herbs in general have more
antioxidant potential than medicinal ones, such
as ginkgo.
7. To boost your calcium, eat sardines
When eaten with their small edible bones, three
small fish (one ounce each) supply 370
milligrams of calcium, more than a cup of milk.
Canned salmon, also eaten with its bones,
supplies nearly as much calcium.
8. Drink tea
It contains enough fluoride to help prevent tooth
decay, and is also rich in substances called
polyphenols, which act as antioxidants and thus
may help protect against cancer.
Tea drinking may also help strengthen bones.
Besides the fluoride, flavonoids and other
compounds in tea may be good for bones. Some
people still worry that tea could weaken bones
because of its caffeine, but several studies have
now shown this is not the case.
