Question description

Do HW in Ansys software and write a report for each HW , follow the instructions.

This HW will go through safe-assign and turnitin so please be careful the work should be %100 originally.

University of Alberta ANSYS Tutorials - www.mece.ualberta.ca/tutorials/ansys/CL/CBT/Truss/Truss.html Two Dimensional Truss Introduction This tutorial was created using ANSYS 7.0 to solve a simple 2D Truss problem. This is the first of four introductory ANSYS tutorials. Problem Description Determine the nodal deflections, reaction forces, and stress for the truss system shown below. Note that Young's Modulus, E, is 200GPa while the crass sectional area, A, is 3250mm2 for all of the elements.
