2. A hydraulic jack is operated by pushing down on a small circular piston with radius of 1.125 in. This action raises another cylinder with area of 284 in². If you push down on the small cylinder with a force of 92 pounds, how much weight will be lifted by the larger piston? 3. In the previous problem, if you were to push the small piston down by a distance of 22 in, by how much would this raise the larger piston? Assume that the fluid is incompressible. 4. Calculate the total pressure a point in the Laurentian Abyss in the Atlantic Ocean, where the depth is 5823 meters (around 20,000 ft!!!). Give the answer in units of A) Pascals, B) psi and C) Atmospheres. [Assume po 14.7 psi = 1.013x10³ N/m²]. 5. If the pressure over a house would suddenly drop by 8.6%, and the inside pressure remained at standard atmospheric pressure, what would be the amount of net force on the roof of the house, assuming the roof is flat and has an area of 1380 ft²_2
