A1: With the help of a hydraulic press, a load of 80 kN is to be lifted. A force of F1 = 200 N is applied to the first piston with the diameter of 30 mm. Calculate:

  1. The required diameter of the load piston in mm
  2. The piston stroke s2, when the fist piston has a stroke of s1= 400 mm.
  3. The pressure within this pressure system in bar and Pascal.

A2:  In the hydraulic brake system shown below, the brake pedal is 30 cm long. The piston on the brake pedal has an area of 5 cm2. The two brake pistons have a diameter of 50 mm. Calculate the total force which brakes the wheel!
