Question

Explain how a hydraulic press is able to multiply forces. Give an example, and show how energy is conserved.

Answer 1

Hydraulic press illustrate Pascal's principle that pressure exerted on a confined fluid is transmitted on diminished throughout the fluid., therefore the pressure exerted on a small piston is transmitted to large Piston because of the large distance larger area the large Piston exert a greater upward force

for example consider a system fitted with a pair of piston one of area 1 square centimetre and other other area 100 square cm if one newton is exerted on small piston than a pressure of 1 Newton per square cm in a transmitted to the larger Piston at the larger piston of force of 1 Newton is exerted over every square centimetre giving a total of 100 Newton in this way force is multiplied by the ratio of piston areas the distance the largest moves however is the reverse ratio in this example if the small Piston moves downward by 1 cm the largest rice only 0.01 cm so (Force X distance) puts into the system is equal to (force x distance) coming out of the system this is consistent with a conservation of energy.
