A hydraulic press has a large circular piston of radius 0.8m and a circular plunger of radius 0.2m. A force of 500N is exerted by the plunger. Find the force exerted on the piston
-
A.
8000N -
B.
4000N -
C.
2000N -
D.
31N
Correct Answer: Option D
Explanation
Pressure on piston = pressure on the plunger
(frac{500}{pi times 0.8 times 0.8}) = (frac{F}{pi times 0.2 times 0.2})
F = 31.25N
F (approxeq) 31N
