Three rods are sustaining a force $F.$ Determine the force along each rod for equilibrium. The forces may

be positive $($tenstion$)$ or negative $($compression$).$

Let the lengths be $L_1=7m,L_2=2\mathrm{.}8m,L_3=3\mathrm{.}1m,L_4=6\mathrm{.}8m,L_5=2\mathrm{.}6m,L_6=6\mathrm{.}2m$ and $L_7=$

$6\mathrm{.}8m.$

Let the Force be $F=700N.$

$N,F_{AC}=,N,F_{AD}=$
