Problem $5$b$.1$

The frame, consisting of two rigid bars, AEC and BDC$,$ supports the

$200$ lb cylinder. The roller at C rests on member AEC but does not

contact pin C or member BDC$.$ The self$-$weight of this frame is $13$l$($b$)/($f$)$t

along of the length of each bar. The pulley has a frictionless bearing

and the weight of the pulley can be neglected. Determine all of the

forces acting on all of the members including the forces on pin D$.$

Answers: R$\_($A$)=45$lb;$,$N$\_($B$)=226$lb;$,$N$\_($C$)=479$lb;

F$\_($C$)=305\mathrm{.}1$lb;$,$F$\_($D$)=282\mathrm{.}8$lb
