28). A hydraulic jack has a car (m = 12,000 kg) on one pad of it (A = 2.7 m$^2$). If the other pad has an area of 40 cm$^2$, how much force on that pad is required to lift the car? If you want to lift the car 2m, how far must the other pad be pushed in?

Step 1
7 m^2 Area of pad B = 40 cm^2 = 0.004 m^2 Acceleration due to gravity (g) = 9.81 m/s^2 The force required to lift the car can be calculated using the formula: Force = Pressure × Area The pressure on pad A can be calculated using the formula: Pressure = Force / Show more…

A hydraulic press in a garage is attached to a platform that is used to lift cars. The press includes a small piston that is attached to a fluid-filled pipe, which opens into a larger chamber under the platform (see image below). If the platform has a radius of 2 m and the piston has a radius of 2 cm, how much force (in N) must be applied to the piston in order to raise an 1800 kg car?
