Find support reactions at 4 and Band then use the method of joints to find all member forces. Let b = 3 m and P = 80 kN.
2) A force, P, is applied to the truss shown to the right. First, determine the support reactions at C and F. Determine the force in member AB in terms of the A В applied force P (specify tension or compression). You must do this problem: (a) first, using method of joints, (b) second, using method of sections. (For part (a), plan ahead: what is the best joint to start with, so you can minimize the number of joints you need to analyze?) (FYI, you can do this problem without a calculator problem.) Ans. C, = 2P/3 (↑), Fx = 0, F, = P/3 (↑) FAB = P/2 (C) 4 m C F E OMONO P 3 m 3 m 3 m
