A hydraulic press has an input cylinder 2.0cm in diameter and an output cylinder 18cm in diameter. (a) Assuming 100 percent efficiency, find the force exerted by the output piston when a force of 160N is applied to the input piston.

A cylindrical tank of radius 5 ft and height 9 ft is two-thirds filled with a liquid of weight density P Ibs./ft³. The work (in ft-lbs.) required to pump all the water over the upper rim is given by the integral (A D25 over 81 pi rho integral subscript 0 superscript 6 left parenthesis 9 minus y right parenthesis y squared space d y (B 25лр (6- у) dy 25 -пр 81 (9- y)y? dy 25 pi rho integral subscript 0 superscript 6 left parenthesis 9 minus y right parenthesis d y

A hydraulic lift in a garage has two pistons: a small one of radius 1.8 cm and a large one of radios of 9.0 cm. If the lift is designed to lift a car with a mass of 2000-kg truck, what minimum force (in newtons) must be applied to the small piston?

Hoover Dam on the Colorado River is the highest dam in the United States at 221 m, with an output of 1300 MW. The dam m m³/s. generates electricity with water taken from a depth of 103 m and an average flow rate of 665 (a) Calculate the power in this flow in watts. X W (b) What is the ratio of this power to the facility's average of 680 MW?
