Figure 1 shows a simple truss structure consists of three members to support the load acting at P. The members are made from steel with 200 GPa Young's Modulus, E and cross section area, A of 6.25x10 m². A design engineer was assigned to analyze the truss using finite element method to ensure that the displacement at P is not exceeding 1 mm in x and y directions. By using finite element method If the truss is divided into three elements, using the finite element method i. Assemble the global stiffness matrix of the truss. ii. Determine the maximum forces in x and y directions at P. iii. Calculate the stress for each element. 300 mm Max displacement = 1 mm Max displacement = 1 mm P 400 mm Figure 1.
