A) Compute the forces on the L shaped support rack from each cylinder. Include free body diagram of each cylinder. B) Compute the reactions on the L shaped support rack at A and B. Include a free body diagram of the support rack.

For the truss, which shows the reactions found at the supports at A and E, answer the following: a)Find the member forces at A and B using the method of joints. b)Find the member forces of CD, GD, and GF using the method of sections.   (ps. this question is from an architectural structures class, I am struggling to begin)

A) Draw a free body diagram of the bar CD. Assume appropriate reactions at C and D in order to keep the problem solvable. The block has a mass of 5 Mg. B) Compute the tension in the cable ADB, ignore the radius of the pulley. C) Compute the reactions at C. 3 m A N B 4 m 4 m D

1) As a part of semester project, a group of students in ENGR 2001 class is tasked with designing the loaded Truss Bridge shown in Figure 1. Students are required to perform member force analysis calculations using the Method of Joints. a) Draw the Free Body Diagram (FBD) of the complete truss and use this diagram to determine the reaction forces at the supports A and D. Note the truss is supported by a roller at D Using the Method of Joints. determine the forces in members: b) AB c) BF d) BE (T 3 State whether the members are in tension or compression. 2m 2 m 1.5 m E A B 11 kN 22 kN -2 m Figure 1 D
