A bracket ABCD with circular cross section AB, a horizontal arm BC parallel to the x0 axis and a horizontal arm CD parallel to the z0 axis (see figure). Arms BC and CD have lengths b1 = 3.6 ft and b2 = 2.2 ft, respectively. The outside and inside diameters of the bracket are d2 = 7.5 in and d1 = 6.8 in. A vertical load P = 1400 lb acts at point D. Determine the: A) The maximum tensile, compressive and shear stresses of the bar CD
B) The maximum stresses of tension, compression and shear of the bar BC.
C) Draw Mohr's circle for the critical stress element from part A)
