A box with weight $W=$

$3\mathrm{.}99[kN]$ is loaded onto a

crane as shown. The

geometry in the figure is

given by $l1=0\mathrm{.}622[m],$

$l2=6\mathrm{.}79[m],$ and $=$

$3\mathrm{.}59[$degree$].$ If the

moment created about

point A due to the weight of

the box cannot exceed

Mmax$=28900[N*m],$

find the following:

What is the maximum

extension $x$ allowed for the

crane?
