Problem $1$

The frame is supported externally by pins at A and F and consists of

four rigid bars: ABC,DEF,CD$,$ and BE$,$ all of which are pinned

together to form a stable structure. The self$-$weight of each

member can be neglected in this case.

Determine all of the forces acting on all of the members.

q$=100$l$($b$)/($f$)$t;$,$a$=3$ft;$,$b$=4$ft

Answers:

R$\_($A$)=(-1350$e$\_(1)+150$e$\_(2))$lb;$,$R$\_($F$)=(1350$e$\_(1)+1200$e$\_(2))$lb

F$\_($BE$)=2250$lb;$,$F$\_($CD$)=600$lb
