The truss shown in the figure below is under a linearly distributed load and is subjected to a point load on the right side, while its left side is fixed. Use the finite element method to solve the weak form for the truss EAue dar - , n) dr - [N vo].) =0 (e) subjected to loading as shown in the figure and determine the displacement at the end and middle of the truss by using two elements with the following linear shape functions: ). 02 = %3D le (+) - n(x) = ax F EA=const.
