Concept #1: Pascal's Law and Hydraulic Lift

Example #1: Hydraulic Lift / Proportional Reasoning

Example #2: Force to Lift a Car

Additional Problems
A hydrolic lift system is power by lowering a weight onto an "input pad" with an area of 100 cm2, transmitting the pressure through hydrolic fluid, which is then used to lift a 10 m  2 platform that a car rests on. If a 2000 kg car is on top of the platform, how much weight must be placed on the "input pad" to raise the car?
The hydraulic lift (the figure below) has a small piston with the surface  A1= 0.039 m2 and a large piston with the surface A2 = 5.0 m2. F1 = 21 N. What force will the large piston provide if the small piston in a hydraulic lift is moved down as shown in the figure? (Express your answer to two significant figures.)
The hydraulic lift (the figure below) has a small piston with the surface  A1= 0.039 m2 and a large piston with the surface A2 = 5.0 m2. F1 = 21 N.  If the small piston is depressed a distance of Δy1, by how much will the large piston rise? (Express your answer to two significant figures.)
The hydraulic lift (the figure below) has a small piston with the surface  A1= 0.039 m2 and a large piston with the surface A2 = 5.0 m2. F1 = 21 N. How much work is done in slowly pushing down the small piston if Δy1= 0.25 m? (Express your answer to two significant figures.)
A hydraulic lift is designed to raise a 900-kg car. The "large" piston has a radius of 36.0 cm and the "small" piston has a radius of 4.00 cm. Determine the minimum force exerted on the small piston to accomplish the task. (Express your answer to three significant figures.)
