Physics Moment of a force: Moment of a force = force x perpendicular distance of the line if action if the force from fulcrum Law of moments: When a body is in equilibrium the sum of the clockwise moments about any point equals the sum of the anticlockwise moments about the same point. Centre of mass: Centre of mass is the point where whole mass of the body assumes to be concentrated. II. If the vertical line through the centre of mass is outside the base it will be a topples but if it’s passed

the same time they get young people they can mold to their own specific needs and make experts out of them. 2. You can work in another country Working as electrical engineer opens you lots of opportunities in other countries. Laws of math‚ electricity and physics are universal and your gained knowledge doesn’t limit you to only the country you studied in. There are a lot of international companies that need electrical engineers‚ also most of them are willing to employ people form other countries

Lesson 11. Topic “Heating effect of an electric current”. Grammar material: Articles. Text: “Heating effect of an electric current”. The production of heat is perhaps the most familiar among the principal effects of an electric current‚ either because of its development in the filaments of the electric lamps or‚ may be‚ because of the possible danger from overloaded wires. As you know‚ of course‚ a metal wire carrying a current will almost always be at a higher temperature than the temperature of

He was born in the Austro-Hungarian Empire‚ in an area now known as Croatia‚ in 1856‚ merely nine years after Edison was born. Tesla also grew up with a dream of working with electricity‚ and he started his career by working for Edison himself. He eventually branched off to create a rival business‚ working against Edison with his own designs. A few of his patented inventions include the basic design for a radio transmitter‚ wireless

Lucy Ellman fantasizes about a world without electricity‚ yet she stumbles upon her own rebutall. To live comfortably in a world without power requires many other human beings to toil without a hint of comfort. This lifestyle was accessible without power‚ but it’s unlikely she would have reaped its benefits. The "mechanical slave" she references was simply known as a "wife" or "servant." I have fantasies of electricitylessness. To live in a steading somewhere‚ equipped with a reliable well‚ vegetable

Life without Electricity In today’s society humankind has become dependent on electricity to be able to live and function. So how would the world be if we couldn’t rely on electricity? There would be no TVs‚ factories‚ cars‚ or even phones. Without electricity we would have to go back to our great great great grandparents’ ways of living. To entertain themselves children would have to learn how to use their imagination. In a world without electricity there would be no video games to play or TVs

Ways to save electricity Nowadays many people have electricity‚ but they don’t know how to use it wisely. There is many way to save electricity. We must use electricity wisely. 1. Way is only use electricity when needed. 2. Replace all of your inefficient incandescent light bulbs with energy efficient CFL bulbs. Replace halogen spotlights with much more efficient and longer lasting LED Spotlight. 3. Hang your clothes out to dry rather than using an electric tumble dryer. Ideally use a spin dryer before

ity C&G 2330 202 REVISION QUESTIONS The relationship between the mass of a body (m)‚ the applied force to the body (F) and the acceleration of the body a. is given by the formula: a. Force = mass x acceleration‚ F = m x a b. mass = Force x acceleration‚ m = F x a c. acceleration = mass x Force‚ a = m x F d. acceleration = mass / Force‚ a = m / F answer: a The SI unit of time is the second. Express 0.00001 seconds in a suitable sub multiple: a. 10 milliseconds‚ 10 ms b. 100 milliseconds
