Question

what is machine and how many types of it ? explain

Answer 1

A machine is a contrivance or mechanism by means of which a force, applied at one part of the machine, is transmitted to another part, in order to secure mechanical advantage for some particular purpose. There are basically six types of machine:

The inclined plane
- used for raising a load by means of a smaller applied force. Mechanical advantage is resisted by some friction.
The lever
- involves a load, a fulcrum and an applied force. Often just a uniform bar.
The pulley
- In simplest form it changes the direction of a force acting along a cord or rope.
The screw
- constructed using the principle of the inclined plane set on a cylindrical or conical surface. A screw-jack lifts heavy weights. Many screw-threads are in everyday use.
The wedge
- a double inclined plane. Mechanical advantage is considerably resisted by friction.
The wheel and axle
- Used to draw water from a well etc. by ropes attached to a large wheel and to a smaller axle. A differential wheel and axle has two-part axle sizes and gains considerable mechanical advantage.

Answer 2

Hi frnd,
A Machine uses power to apply force and control movement to perform an intended action. They can also include performance and plan movement, often called mechanical systems.
There are basically six types of machine.

1. Inclined plane _ used for raising a load by means of a smaller applied forced.

2. The lever involves a load, fulcrum and applied force....

3. The pulley in simplest forms changes the direction of a force acting along a cord or rope.

4. The screw..

5. The wedge..

6. The wheel and axe..

I hope this, help u my frnd!
