- Help please 3 decimal places. and box the final answer. Please dont make it complicated Determine the resultant R of the Four forces acting on the simple truss. The Fourth force is acting on the node where the 25 KN is at and is directed upward with a magnitude of 15 KN. Specify the points on the x- and y-axes through which R must pass.(image attached) 1. Find the force in members AB, BC, BD and CD. 2. Find the absolute vertical displacement of joint C (in inches). Use principal of virtual work. Given: EA= 2000 k for members AB, BC and BD.
