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 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 4 m D E joints you need to analyze?) (FYI, you can do this problem without a calculator problem.)
