1. A hydraulic system is represented schematically by this picture, in which a force F1 acting on a small piston of area A1 can support a car on a large piston of area A2 which applies an upward force F2. The small piston labeled A1 has a radius of 0.012m, and the large piston holding up the car has a radius of 0.15m. (Both are cylindrical.) The height h is equal to 1.1m, and the oil used to fill the system has a density of 850kg/m3. (a) The car and large piston together have a weight of 20500N. What is the (gauge) pressure they produce at point B, the lower surface of the piston? (b) What is the pressure at point A, on the other side of the system? (c) What is the pressure at the lower surface of the small piston? (d) What force F1 is needed to support the weight of the car? (That is, what force is necessary to produce the pressure that you found in part (c))?
