Fig. Prob. $2$

For the stadium truss shown in Fig. Prob. $3,$

$($a$)$ identify six zero force members

$($b$)$ calculate the forces in members AJ$,$ KM$,$ IM

and IL$,$ and state if the members are in tension

or compression.

$($c$)$ explain why the forces in members ML and

ON should be equal in magnitude and sign.

$($d$)$ FOR BONUS of $3\%,$ what is the value of the

force in members ML and ON and are these

two members in tension or compression?Prob. $1.$ Determine the reaction forces required to support the truss, shown in Fig. Prob. $1.$
