Question

2.34 The solid, continuous round bar shown in Figure P2.34 can be viewed as composed of a straight segment and a curved segment. Draw free-body diagrams for the segments 1 and 2. Also, determine the forces and moments acting on the ends of both segments. Neglect the weight of the member Round bar 2 90

Answer 1

sigma F = 0 Implies F - P = 0 Implies F = P sigma M_A = 0 Implies M_A - PL = 0 Implies M_A = PL Implies Reaction forces at the fixed end of curved segment sigma F_y = 0 Implies - P + R = 0 Implies R = P sigma M_B = 0 Implies M_B - P (L + R) = 0 Implies M_B = P (L + R) Now, let us combine the above two figures to draw the FBD of segment (2)
