1. For the truss shown, a = 4 m, b = 3.5 m, c = 5m
a) Use method of joints to solve for internal forces in DJ and JU.Consider the internal force at TI equal to 1.2 kN, COMPRESSION.
b) Use method of sections to solve for internal forces in WX and WL. Consider the force in member TU equal to 2. kN, TENSION.
