Expert Solution
Step 1: Introduction

To determine the torque in the shaft and the angle of twist at a point

given

radius of gear b=r subscript b equals 1.25 space i n equals 0.03175 space m

radius of the gear c, r subscript c space equals 4.60 space i n equals 0.116 space m

radius of the shaft ab, r subscript 1 space equals 1 space i n space equals 0.0254 space m

shaft of the radius cd, r subscript 2 equals space 0.75 space equals 0.01905 space m

shear modulus G equals 12000 space k s i space equals 8.27 cross times 10 to the power of 10 space P a

torque in section A is T subscript 1 space equals 1100 space i n l b equals 124.283 space N m

length of the shaft, 62 space i n space equals 1.574 space m
