Question

What is the meaning of lever in simple machine?

Answer 1

The answer is.......A simple machine consisting of a bar that pivots on a fixed support ,or fulcrum and is used to transmit torque.A force applied by pushing down on one end of the lever results in a force pushing up at the other end...Levers like gears can thus be used to increase the force available from a mechanical power source.
