Diagram shows two vertical shafts marked 1 centered on the x axis and shaft 2 centered on the x prime axis which are twisted inward with a gear marked A on shaft 1 at a height of 400 millimeters from the base B. A gear marked C is on the shaft 2 at a height of 400 millimeters from the base D. The diameter of the gear A is 150 millimeters and the diameter of the gear C is 100 millimeters. A torque T is applied above the gear A on the shaft 1 in the counterclockwise direction.
The shear stress in shaft
(2)
is:
