A single horizontal force P with a magnitude of 150 lb is applied to end D of lever ABD. Knowing that portion AB of the lever has a diameter of 1.2 in, determine:
(a) Equivalent Force-Couple System at Point H and internal forces. Draw free body diagram. [2+2+2]
(b) Show these stresses on a general stress element for point H. [2]
(c) Normal and shearing stresses located at point H and having sides parallel to the x and y axes. [2+2+2]
(d) Principal planes and principal stresses at point H. [2+2+2+2]
(e) Plot the Mohr's circle labeled with values calculated, and Rotated 2D stress element for principal stresses. [4+4]
