list the types of machine we have and explain them
Answers
Answer:
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 the 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 heavyweights. 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 have two-part axle sizes and gains considerable mechanical advantage.
