For the sets of given stresses on an element given in Table 4–2, draw a complete Mohr’s circle, find the principal stresses and the maximum shear stress, and draw the principal stress element and the maximum shear stress element. Any stress components not shown are assumed to be zero. 

Refer to Figure P3–50. For the shaft ABC, create a stress element on the bottom of the shaft just to the left of section B. The torque applied to the shaft by the crank is resisted at support B only. Draw the Mohr’s circle for the stress element. Use D = 50 mm.
