For this learning task, you will investigate Pascal's principle and the relationships between force, area, pressure, and the distancetravelledby pistons in cylinders using the simulation of a hydraulic press below.

1. Select a piston head area of 0.050 for cylinder 1 and 0.070 for cylinder 2.
2. In a moment, you will place a 10.0 kg mass on the cylinder 1 platform, but first, complete a calculation using one of the equations introduced with Pascal's principle to predict how far piston 2 will move relative to piston 1 once the mass is placed on the cylinder 1 platform.
3. Place a 10.0 kg mass on the cylinder 1 platform and record how far each piston moves.
4. Compare the movement of the pistons to your prediction.
5. Complete calculation using one of the equations introduced with Pascal's principle to predict the amount of mass to be placed on the cylinder 2 platform in order to balance the press, and have the pressure created by the masses on both platforms be equal.
6. Place the mass you predicted would be necessary on the cylinder 2 platform. Record the result.
7. Complete calculation to determine the increase in pressure in the hydraulic fluid as a result of the mass that was added to the platforms.
8. Reset the simulation and repeatSteps 1-7, but, inSteps 1 and 2 you must choose different piston head areas and a mass other than 10.0 kg to add to the cylinder 1 platform. Note that you might need to try the cylinder 1 platform mass a couple of times. Depending on the piston head areas and cylinder 1 platform mass you choose, you might wind up needing to add, e.g., a 0.5 kg mass to balance it out. If this is the case, choose a larger mass for the cylinder 1 platform and try your calculations again.
