2. Recall the example problem we looked at in class (lecture 8) of a hanger on a wall supporting a weight, similar to figure 2. In class, we took the angle of the diagonal member to be 0 = 30° from the horizontal. Here, we fix the height of the truss H, while we allow and L to potentially change. (a) Determine the force in each member of the truss in terms of the variable 0. You may refer to the lecture notes but show all your working and final expressions clearly. (b) (c) setting Check that your expressions in part (a) are correct by 30A and comparing to the lecture notes. H = As you increase the length L of the hanger, how do and the forces in each member change (increase or decrease)? Which member would you expect to fail (break) first if you con- tinue to increase-L? 1 B L- P-100 N Figure 2: Problem 2: Wall hanger
