A research submarine with the crew of 15 people has beached itself on the bottom of the ocean, in shallow waters off the Australian coast, to collect sand samples to assess the impact of air pollution on the sea floor. The research submarine is designed to be lifted by ropes and transported by mother ship to its next location. As the lead engineer it is your job to h implement the plan to retrieve it to the mother ship. Part of the design incorporates support ro connecting the submarine to a boat on the surface. Your task is to determine the force requ to pull the submarine off the seabed. Its dimensions have been provided below. The density of the water at this level is Pwater = 1000Kg/m. The submarine's density is Psub = with the surface area of 440m. 1500Kg/m Formulas: 5m F 25m Volume of a cone Volume of a cylinder Vcylinder = h Volume of a sphere 4r Vcone = 3 Vsphere = 3 3.8m Buoyancy Force F = g*p*Vsub a) Complete the free body diagram (forces on the submarine) and calculate the minimum force on the rope (F) to recover the submarine from the sea floor. Show full working and state any assumptions that you have made. b) What can you do to improve the recovery process in this situation and justify your reasoning (state your assumptions).
