Questiоn 4 The diаgrаm shоws а device called a hydraulic lift. The hydraulic lift cоnsists of a tube of oil with a piston at each end. (image source: pearson.co.uk) 4.1 Calculate the pressure difference between the bottom of piston X and the bottom of the oil. [density of oil = 820 kg/m3] (3) 4.2 A 24 kg mass is placed on piston X. Calculate the weight of the 24 kg mass. (3) 4.3 Piston Y starts at rest, rises slowly and then comes to rest. State how the following energy stores have changed from before the motion to after the motion is complete. 4.3.1. Gravitational potential energy of piston X 4.3.2. Gravitational potential energy of piston Y 4.3.3. Kinetic energy of piston Y (3) TOTAL QUESTION 4: [9]
