Consider the configuration of a hydraulic jack being used in a car repair shop, as shown in the figure. The piston has an area of A1 = 0.8 cm2 and A2 = 0.4 m2. A car that weighs 13,000 N is to be jacked up. Calculate the force F1 in newtons required to hold the weight of the car. Hydraulic oil specific gravity is 0.87 and h = 2 m. Neglect the weights of respective pistons and platform where the car is placed.
