answer 18.11 and 18.12
18.11 A steel ring with an outside diameter of 150 mm and an inside diameter of 100 mm is shrunk onto another steel ring with an inside diameter of 50 mm. An axial force of 56,54 kN is needed to push the rings apart. Calculate the pressure at the mating surface and the shrinkage allowance given that both rings are 20 mm thick and the coefficient of friction between the mating surfaces is 0,2. Using...

solution and in Celsius An air bubble of radius 5.5 cm is released from the mouth of a diver. At the diver's depth the pressure is 1.20 atm . (We'll learn in chapter 13 why the diver's depth affects the pressure.) As it rises to the surface, the air inside the bubble does 8.938 J of work. The bubble rises so quickly to the surface that this process can be treated...
