JAMB Physics 1985 Question 15

Question 15

Pressure

The areas of the effort and load pistons of a hydraulic press are 0.5 m2 and 5 m2 respectively. If a force F1 of 100 N is applied on the effort piston, the force F2 on the load is

  1. A.10 N
  2. B.100 N
  3. C.500 N
  4. D.1000 N
  5. E.5000 N
Show the answer and explanation

Answer: D (1000 N)

Explanation

The pressure is the same on both pistons: 100/0.5 = F2/5, so F2 = 1000 N.
