Simple Machines
What is simple machine?
Here you all think that what is simple
machine. The machines which are simple in construction that kind of machine
are known as simple machines. A simple machine is a mechanical devices that
changes the direction or magnitude of a force. This kinds of machines are use
mechanical advantage for multiplying force.
How simple machines are works?
The simple machines are works on the principal of forces. A simple
machine uses a single applied force to do work. If we ignore the friction
losses, then applied forces to simple machine is equal to output forces. That means
we get 100% output of input. So, mechanical efficiency of simple machine we get
100%. But in actual life problem it can not possible. The ratio of output
forces to input forces known as mechanical efficiency of the machine. In above
case we get mechanical efficiency 100%. The machine can increase output force,
at the cost of proportional decrease in distance moved by load.
For example: lever, pulley, wheel and Axle, inclined plane,
wedge, screw etc.
The science is great but there are several grammar issues in this post. "What is simple machines?" Should be, "What are simple machines?" Second sentence at the top should be, "...and introduces top technology..." "How simple machines are works?" should probably be "How do simple machines work?" There are a number of other sentences that are less than clear. I am guessing English is your second language.
