The steel beam ABCD shown is supported at C as shown and supported at B and D by steel bolts each having a diameter of 5/16 in. The lengths of BE and DF are 2 and 2.5 in, respectively. The beam has a second area moment of 0.050 in4. Prior to loading, the nuts are just in contact with the horizontal beam. A force of 500 lbf is then applied at point A. Using procedure 2 of Sec. 4€“10, determine the stresses in the bolts and the deflections of points A, B, and D. For steel, let E = 30 Mpsi.
