CRANE SLING PROBLEM

$13-2.$ The beam has a weight of $700lb.$ Determine the shortest cable ABC that can be used to lift it if the maximum force the cable can sustain is $1500lb.$

$1.)$ This is a Concurrent Problem

$2.)$ The Hook$-$load $($B to Roof$)=700$ # $($see page $5$ of the lecture notes$)$

$3.)$ Draw a Concurrent FBD @ Point $"B"$

$4.)$ The Cable Loadings $BA$ and $BC$ are Equal $)$

$5.)$ Set the Cable Loadings for $BA=1,500$# and $BC=1,500$#dots

$6.)$ Solve for the angle Theta
