Straw Pressure If you put your finger on top of a drinking straw submerged in water, you can hold the water in the straw when you draw it out of the water. Draw a force diagram to show why this happens If the water in the straw is 10cm high, what it the pressure at the top and the bottom of the straw?

Copyright © 2008 Pearson Education, Inc., publishing as Pearson Addison-Wesley. Lifting a car The hydraulic lift at a car repair shop is filled with oil. The car rests on a 25-cm-diameter piston. To lift the car, a force is applied to push down on a 6 cm diameter piston. What force will support a 1300 kg car level with the small piston? If you lift the car up by 2m, by how much do you need to push the small piston?
