Question

A hydraulic jack has an output piston

of area 0.100 m2. A 55.8 N input force
creates 419 N of output force. What is
the area of the input piston?

Answer 1

Step-by-step explanation:

You want the area of the output piston not the input piston. The input piston creates a pressure equal to

55.8 N/0.1 m^2 = 558 N/m^2. This pressure is transmitted through the hydraulic fluid and applied to the output piston. The pressure exerted on the output piston is equal to 419 N/Am^2. Set this equal to the applied pressure and solve for A, the area of the output piston.

419/A = 558 , A = 419/558 = 0.751 m^2

Answer 2

0.0133 m^2

Step-by-step explanation:

55.8/419=0.133

0.133*0.100= 0.0133

Hope this helps!
