Truss$-$joint method

$6-5.$

Determine the force in each member of the truss and state

if the members are in tension or compression. Set

$P_1=7kN,P_2=7kN.$

Use joint method

Ans.

$F_{AD}=9\mathrm{.}90kN(C),F_{AB}=7kN(T),F_{DB}=4\mathrm{.}95kN(T),F_{DC}=14\mathrm{.}8kN(C),F_{CB}=10\mathrm{.}5kN(T)$
