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
2) A cantilevered truss is loaded as shown below. Using method of sections determine the force in member BC. Leave your answer in terms of P. Specify tension (T) or compression (C). (FYI, you do not need a calculator to do this problem.) (Hint: you do not need to find the support reactions to do this problem.) Ans: FBC = (9P)/4 (T) 6 m 6 m 4 m D E 3 m 6 m 3 m
For the next Trusses, compute the axial forces in the selected sections. Compare the result with the method of joints. (Check the image for the trusses)

Answer with Complete Solution.
please explain how to solve and include FBD
Please help me with this one, thank you!! (for clarification the 2nd force is 1.5P)
Itranscript Required Information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. The truss shown consists of six members and is supported by a short link at A, two short links at B, and a ball-and-socket at D. Consider load of 420 lb applied at C. 10 ft Bol 24 t Determine the force in each of the members.
