4. A m = 80 kg student wants to elevate a M = 3300 kg elephant on a hydraulic lift filled with water (p = 1000 kg/m) to a height of 10 cm (labelled as h in the diagram). a. mkg M kg 12 1 If the radius of the student's cylindrical pipe is r = 0.3 m, determine the radius of the elephant's pipe, r? b. If we replace the water with oil (Poll = 900 kg m3), will the relative height difference, h, between the student and the elephant increase, decrease, or stay the same? Explain your reasoning. 4.
