Answer

It doesn’t violate energy conservation.

Work Step by Step

The area ratio is 100:1, so the output force is 100 times larger than the input force. However, the smaller force is exerted through a distance 100 times greater than the large force is exerted. The amount of work is the product of force and distance. The work output is equal to the work that is input – energy is conserved.
