Question

1. Refer to Problem 4-1 a. Determine the axial stress in the shaft. b. How much does the shaft shorten due to the thrust from the propeller? c. If v 0.3, how much lateral strain would you expect? d. How much change would you expect in the diameter of the shaft? 4-1. The ship is pushed through the water using an A-36 steel propeller shaft that is 8 m long, measured from the propeller to the thrust bearing D at the engine. If it has an outer diameter of 400 mm and a wall thickness of 50 mm, determine the amount of axial contraction of the shaft when the propeller exerts a force on the shaft of 5 kN. The bearings at B and C are journal bearings Prob. 4-1
