Plan the Solution  
scene 2 of 8
The figure shows a vertical bar of width 50 millimeters. An inclined section labeled a a is shown making an angle 36 degrees with the vertical. The load at the bottom end of the bar is directed vertically downwards.

Several approaches could be used to determine the maximum load P. For this example, the following procedure will be used:

7. The two values computed for P are then compared. The smaller value of P controls since this load will produce stresses that are less than or equal to both the allowable normal stress limit and the allowable shear stress limit.
