Introduction to Hydraulic Systems (6)

What is pressure?

• Weight of an object

• Force acting on a given area

• The area of a pair of snowshoes

• Gravity

A hydraulic press shows what in action?

• Pascal's law

• Murphy's law

• The Peter Principle

• TRUE

• FALSE

Pascal's Law explains how __________.

• Fluid stays in a barrel

• A small jack can raise a two-ton car

• An oil tanker floats

• To calculate the force of gravity

Pascal's Law states that any change in pressure in an enclosed fluid is applied equally to all the fluid in the enclosure. Is this statement TRUE or FALSE?
