The shaft of Fig. 1 is simply supported at A and B and is keyed against rotation at A.

(a) Draw a view of the element on the top surface of the shaft at B with sides parallel to the x and y axes. Show arrows and numerical values for all stresses acting.

---

(b) Draw the element at B properly oriented to give the maximum shearing stresses. Show arrows and numerical values for all stresses.
