In the figure on the right, piston 1 has r,-0.012 m and of negligible weight and piston 2 has a r₂=0.15m. If the combined weight of the car and the plunger is 20500N and the density of the oil 800 kg/m³, what should be the force, F₁, needed to support the output plunger if a)both pistons are at the same level. b)if piston 2 is 1.10m lower than piston 1.
