I need help with Pascals Principle!?

Pascal‘s principle states that fluid pressure in transmitted undiminished in every direction for a closed system. Using this principle, a hydraulic lift supports a 12,000-kg car, supported over an area of 5.0m2. If the input area is 0.010 m2, what force is needed to lift the car?

Answer:

the cable snapped. it has nothing to do with your regular brakes. all it,s for is for parking on steep grades.
From the sounds of it you've blown one of the rear cylinder seals. If you look under from the back at either brake back plate you might see a dark patch where the fluid is leaking out. Wheels and drums off time.
First the force that car produces equals mg that is 12000*9.81117720 Newton on the surface of 5 m2. There is a equation here F/Af/a. In this problem F117720 N, A5 m2, a.01 m2, f? (we are lookin for this). Applying the equation f235.44 N the force you need to lift the car. I hope it would be useful.
