Problem 1: (20 Points) Shaft AB is fixed at end B and subjected to the uniform distributed torque over the length L and a concentrated torque at A as shown below. a) Draw the torque diagram for the shaft b) If the material of the shaft has tallow=250 MPa, determine the minimum diameter of the circular shaft c) Assume the diameter of the shaft is 100 mm, determine the angle of twist of end A with respect to end B. Use G = 75 GPa d) Determine the number of bolts necessary to fix the base of the shaft to the rigid wall at end B. The radial distance from the center of the shaft to the center of each bolt is uniform and equals to 400 mm. Each bolt has a diameter =10 mm and tallow = 220 MPa. Before starting the solution, use your student ID and table given below to find the value of the length L. L: 4.3 5 kN-m/m 2m A 3 kN.m
