The bracket is held to the wall using three A-36 steel bolts at B, C, and D. Each bolt has a diameter of 0.4 in. and an unstretched length of 2 in.
If a force of $P = 550 lb$ is placed on the bracket as shown, determine the force developed in bolt B. For the calculation, assume that the bolts carry no shear; rather, the vertical force of 550 lb is supported by the toe at A. Also, assume that the wall and bracket are rigid. A greatly exaggerated deformation of the bolts is shown in the figure below (Figure 1).
