An automobile having a mass of 1750 kg is placed on a hydraulic lift in a garage. The piston lifting the car is 0.244 m in diameter. A mechanic attaches a pumping mechanism to a much smaller piston, 1.50 cm in diameter, which is connected by hydraulic lines to the lift. She pumps the handle up and down, slowly lifting the car. What is the force exerted on the small piston during each downward stroke?
