2. Objective: TLW state and explain Pascal’s principle and relate the principle to hydraulic devices. TLW state and explain Pascal’s principle and relate the principle to hydraulic devices.

3. MI #1: What is Pascal’s Principle? Pascal’s Principle states that fluids in a container exert pressure equally in all directions. Pascal’s Principle states that fluids in a container exert pressure equally in all directions.

4. MI #2: Hydraulic Devices Hydraulic devices use different sized pistons to multiply pressure. Hydraulic devices use different sized pistons to multiply pressure. Pressure is applied to the smaller piston, which is multiplied because of Pascal’s Principle. Pressure is applied to the smaller piston, which is multiplied because of Pascal’s Principle.
