Question

In a hydraulic lift system, what must the surface area of a piston be in cm² if a pressure of 1300 kPa is used to give a desired upward force of 20000 N?
F1/A1 = F2/A2​

Answer 1

Explanation:

according to Pascal's law

F1/A1= F2/A2. (1)

given pressure P1 =F1/A1=1300kPa = 1300×10^3pa

upward force F2= 20000N

A2=?

using. (1)

1300× 10^3 = 20×10^3/A2

A2= 2/130

A2= 0.01538N/m^2

hope this helps...
