Question

determine the force in each member of the truss and state if the members are in tension or compression. Set P1= 400lb, P2= 400lb, P3= 0.

I dont know how to solve this but the book gives the answers for reference.

Answers should be: Fab= 377 lb(C), Fbf= 267 lb(T), Ffc= 189 lb(T), Fed= 56.4 lb(T), Faf= 190 lb(T), Fbc= 267 lb(C), Ffe= 56.4 lb(T), Fec= 0, Fcd= 189 lb(C)

Please show all work! Thanks!
