Use whatever method you like to find the force in each member of the truss shown in Figure $13$ and specify whether the member is under compression or tension. The angle at joint $A$ is $90.$

Figure $13$: Problem $13$

The truss shown in Figure $14$ is pin$-$supported at A and roller$-$supported at $B.$ Use whatever method you like to find the force in members $BC,BE,CD,$ and $CE,$ and determine whether each member is under compression or tension. The truss is symmetric with respect to a vertical line through joint $E.$
