For the mechanical part shown in Figure 2, P = 1200 N, F= 2000 N, and T = 12500 N.mm. The circular rod is made of AISI 1006 cold-drawn steel and the recommended design factor is 2. a. Draw the stress elements at the indicated locations A and B, showing all the acting stress components in terms of diameter of the circular rod. b. Calculate the values and directions of both the principle stresses and the maximum shear stresses in terms of the diameter of the rod. c. What is the safe diameter value, assuming that your designed based on (maximum shear stress theory and maximum distortion energy theory) B 100 mm Figure 2 70 mm
