The shaft carries the steady loads shown and does not rotate.
a) For the element at point A, draw a cub that shows the states of stress and use Mohr's circle to compute the principal normal stresses for this location.
b) For the element at point B, draw a cube that shows the state os stress and use Mohr's circle to compute the principal normal stresses for this location. Be sure to include the effect of transverse shear at this point.
Description of Shaft in order to do Free Body Diagram:
The shaft is a total of 11 inches with a diameter of 2 inches. There is a T=7000 in-lb at the end of the rod going counterclockwise, a P=2000 lbs 5.5 inches from the end of the rod and this point on the rod is section A or point A. Then section B or point B is 8.25 inches from the end of the rod and 2.75 inches from point A. Finally there is T=7000 in-lb going clockwise at the opposite end of the shaft.
