A hydraulic press has a ram of diameter 200 mm and a plunger of diameter 40 mm. If a force of 60 N is applied on the plunger, what is the approximate weight that can be lifted by the ram?
Options:
(A) 1500 N
(B) 2500 N
(C) 3750 N
(D) 4500 N
Correct Answer:
(C) 3750 N
A hydraulic press works based on Pascal’s Law, which says that pressure applied to a fluid in a closed system is transmitted equally in all directions. This allows a small force applied on a small area (plunger) to lift a heavy weight on a larger area (ram).
