A hydraulic lift in the shape of the letter U, two pistons are formed, one with a larger diameter and other with a smaller. If the diameter of the smaller piston is 4.0 cm and the diameter of the larger piston is 40.0 cm, what weight can the larger piston support when a force of 250 N is applied to the smaller piston?
Fluid pressure = Force/Area and is the same in both tubes. The tube with larger area can support 100 times more weight weight.
P on piston 1 should equal to P on piston 2
Remember P = F/A
Plug your values into this:
F1/A1 = F2/A2
The weight is same as the force because it's the only vertical force opposing it
