Problem 2 A stepped solid shaft ABC is fixed at points A and C, as shown in the figure, and is subjected to two extemal torques, with the senses and locations shown in Figure 1. The lengths of each section and the corresponding diameters are given in the figure, and it is known that the shear modulus is constant along the length of the shaft. Figure 2. Stepped shaft with external torques. a) Find the maximum absolute shear stress in the shaft assuming T; = To and T2 = R*To. b) Now, again assume T; = To and T2 = R*To, but that the value of To is unknown. If the allowable shear stress in the shaft is equal to Tanow, What is the maximum value of T, that can be used when loading the shaft? Take d, Take To 1 in, do = 2 in, and L = 15 in. 10 kip*in, R = 2, and Tajiow = 12 kSi. Question 13 5 pts If compatibility is written as Ta=C1*Tct+Co after applying load-displacement relations, find C
