Expert Solution
Step 1: Given data

straight tau equals Tc over straight J
straight J equals fraction numerator straight pi cross times open parentheses straight d subscript 0 to the power of 4 minus straight d subscript straight i to the power of 4 close parentheses over denominator 32 end fraction
straight c equals straight d subscript 0 over 2
straight d subscript straight i over straight d subscript 0 equals 0.9
therefore comma space bold d subscript bold i bold equals bold 0 bold. bold 9 bold cross times bold d subscript bold 0

bold for bold space bold problem bold space bold 2 bold comma
Max. space shear space stress comma bold space straight tau equals 150 space MPa
Torque comma space straight T equals 750 space straight N. straight m
