SITUATION $7-$

A crane supports the load $W$ as shown.

If $W=28kN$ find the total reaction at $B(kN)$ neglecting the weight of the boom.

A$.42\mathrm{.}65$

B$.48\mathrm{.}25$

C$.40\mathrm{.}12$

D$.45\mathrm{.}96$

If the allowable tension of cable $AC$ is $52kN,$ find the maximum value of $W$ in $kN.$ Neglect the weight of boom.

A$.65\mathrm{.}8$

C$.60\mathrm{.}1$

B$.69\mathrm{.}3$

b$.62\mathrm{.}4$

If the boom $($mast$)$ weighs $10kN$ and the allowable tension of the cable $AC$ is $52kN,$ find the maximum value of $W.$

A$.61\mathrm{.}8$

l$.57\mathrm{.}4$

B$.52\mathrm{.}3$

D$.59\mathrm{.}4$
