A 13,000-N vehicle is to be lifted by a 25-cm diameter hydraulic piston.What force needs to be exerted on a 5.0 cm diameter piston to accomplish this? Assume the pistons each have negligible mass.
A)260 N
B)520 N
C)2600 N
D)5200 N

The force exerted by the smaller piston is calculated using the principle of hydraulic systems: F1/A1 = F2/A2. The area of the pistons is proportional to the square of their diameters. Solving for F1 gives 520 N.
