Problem $2$

The truss is supported externally by a pin at A and a roller

support at $E.$

The weight of each member can be neglected.

Determine the magnitude of the axial force in each truss

member and state whether it is in tension $(T)$ or

compression $($C$).$

Summarize your results at he end.

Answers

$R_S=R_2=1150N,R_1=R_A=(-1200e_1+1950e_2)N$

$F_1=F_{av}=3250N(C),F_2=F_{nc}=3250N(C),F_3=F_{cDL}=1916\mathrm{.}66N(C)$

$F_4=F_{\frac{c}{G}}=1533N(T),F_3=F_{ct}=1533N(T),F_b=F_{AI}=3800N(T)$

$F_7=F_{MH}=2000N(C),F_s=F_{CI}=1922\mathrm{.}96N(T),F_q=F_{CL}=1500N(T)$
