Question

What do you understand by simple machines?

Answer 1

1. A mechanical device that changes the direction or magnitude of a force is known as a simple machine.
2. A machine is a device by which we can either overcome a large resistive force at some point by applying a small force at a convenient point and in the desired direction or by which we can obtain a gain in speed.
3. In general terms, they are defined as simple mechanisms that make use of leverage or mechanical advantage to multiply force.
4. Simple machines have few or no moving parts to modify motion and force.
5. The most notable among these are the six simple machines: the inclined plane, the wheel and axle, the pulley, the lever, the screw, and the wedge.
