Question

In a hydraulic system, the pressure on the large piston is ____ the pressure on the small piston.

a.
greater than
b.
less than
c.
the same as
d.
not related to

Answer 1

The correct answer is option c. "the same as" In a hydraulic system in order to have an equal flow you have to exert a greater force on the large piston than in the small piston, because of the differences in each piston diameter. However the pressure resulting between large and small pistons is the same.
