```									Pascal’s Principle

1. Write Pascal’s Principle below.

2. Write a short paragraph explaining why squeezing a balloon is a demonstration of
Pascal’s Principle.

3. Hydraulic pumps can be used to lift heavy objects by multiplying force. You might
think that you are getting something for nothing when you can push on a pump and lift a
car, for example, but that’s not the case. The pressure at one end of the pump is
proportional to the other end of the pump that does the lifting and proportions are equal.
Try the problems below. You must show your work and include units!

a. You push a hydraulic pump with a force of 10 N over 5 m2, what is the force at the
other end of the pump if its area is 40 m2?

b. You push a hydraulic pump with a force of 25 N over 10 m2, what is the area at the
other end of the pump if the force at that end is 75 N?

c. If a hydraulic pump lifts a car with a force of 1,000 N over an area of 600 m2, and the
other end of the pump has an area of 100 m2, what is the force at the other end?
