EXPLAIN STEP BY STEP. PROBLEM $6\mathrm{.}10$

Determine the force in each member of the truss shown. State

whether each member is in tension or compression.

This problem was solved in Recitation $-$ Study and follow the given

solution.

In addition, also do the following:

$($a$)$ This is a cantilever truss, supported at A and E$.$ Sketch the

conceptual "segmentally linear" deformed state of the truss.

$($b$)$ Compute the "overturning clockwise moment" exerted by the

applied load about any point along the line AE$.$ Then show that the

horizontal reactions at A and E define a couple $(2$ equal vectors in

opposite directions$),$ and that the "resisting counterclockwise

moment" exerted by this couple equilibrates the overturning

moment by the applied loads.

$($c$)$ Reflect and Think: Sketch a cantilever beam that can replace

this truss with the same span and applied concentrated

loads. Then, compute the reactions of the equivalent cantilever

beam, and show that the moment reaction at the support is "equal

to the resisting moment" in the truss. Also, that the vertical

reaction is the same as in the truss. Sketch the deformed state of

the beam.
