nvm, i figured it out thanks a lot
i kinda have a new problem
i can't figure out where zero forces in trusses come into play, i mean how do i know which forces are zero force members or not?

thats the problem i m working on
so far i have drawn the free body diagram of the truss
found the 2 horizontal forces in the 2 corner joints
right now i m starting from point A, and considering the first triangle ABC,
but like...
While solving for problems involving trusses using method of joints, how do i know which member is in compression and which is in tension?
any help would be appreciated, this stuff's been bugging me for quite some time
thanks and god bless
