5)Determine the forces in all members of the truss. There is a pin at A and a roller at D. In answers for truss forces remember you must always indicate if a member is in tension (T) or compression (C); for example, if there was a member JK carrying a 2 kip compressive load the answer would be FJ = 10 K (C) 3 m G 10 kN 6kN E -2.5 m- -1.5 m-1.5 m- -2.5 m
