Write a Matlab program to determine the reaction forces and force in each member of the truss shown in the figure below to at least 5 significant figures. Identify which force corresponds to which member and indicate which members are in tension and which are in compression. Include a write up showing the derivation of the equilibrium equations used in your program. Check your solution by verifying that the entire structure taken as a free body is in equilibrium. 1.6 m 1.6 m 1.6 m 1.6 m 1.6 m 1.6 m 1.2 kN 2.4 kN 2.4 kN 1.2 kN 2.4 m 0.9 m 2.4m '1.8 m 1.8 m 1.8 m 1.8 m
