In a hydraulic lift a force F1 = 510 N is applied to a piston

with area A1 = 1200 cm2. If the force on the
other piston is 2168 N,

find the area of the other piston

• 0.51 m2 = 5100 cm2
  

• 0.21 m2 = 2100 cm2
  

• 0.62 m2 = 6200 cm2
  

In a hydraulic lift a force F1 = 320 N is

applied to a piston with area A1 = 0.07 m^2.
