Ansys APDL: For the given truss, a horizontal load of P=4000N is applied in the X-direction at node 2. a) Evaluate the stresses in the elements b) Determine the reaction force at node 2 in the Y-direction Cross Sectional Area, A = 0.15m X 0.15m Young's Modulus, E = 2.1 X 108 KN/m2 Poisson's Ratio = 0.3

Ansys APDL A small railroad bridge is constructed of steel members, all of which have a cross-sectional area of 3250 mm2. A train stops on the bridge, and the loads applied to the truss on one side of the bridge are as shown in the below figure. Estimate how much the point R moves horizontally because of this loading. Also determine the nodal displacements and element stresses.
