Question 15

Pressure

In a hydraulic press, a force of 40N is applied on the effort piston of area 0.4m2. If the force exerted on the load piston is 400N, the area of the large piston is

  1. A.8m2.
  2. B.4m2.
  3. C.2m2.
  4. D.1m2.
Show the answer and explanation

Answer: B (4m2.)

Explanation

Pressure is the same on both pistons: 40/0.4 = 400/A, so A = 4 m2.
