Problems $6\mathrm{.}2\mathrm{.}3$ and $6\mathrm{.}4\mathrm{.}3$

$($a$)$

$6\mathrm{.}2\mathrm{.}3.$ The truss is attached to the ground at A with a rocker and at $B$ with a pin connection $($E$6\mathrm{.}2\mathrm{.}3).$ Additional loads acting on the beam are as shown. Based on informaDion in Table $6\mathrm{.}1,$ what loads do you expect to act on the truss at A due to the rocker connection? What loads do you expect to act on the truss at $B$ due to the pin connecEion? Present your answer in terms of a sketch of the truss that shows the loads acting on it at A and $B.$ Also comment on whether the sketch you created is or is not a freebody diagram.
