For the assemblages shown in the figures, determine the nodal displacements, the forces in each element, and the reactions. Use the direct stiffness method for all problems.

For the plane truss with inclined supports shown, solve for the nodal displacements and element stresses in the bars.

Use Galerkin method to solve the following second order linear ordinary differential equation for a linear boundary value problem:

$\frac{d^{2}y}{d{x}^2}+Q(x)y=F(x),$xin$[0,1]$

with the boundary conditions: $y(0)=0,y(1)=A.$ Solve all the problems for Computational stractural Mechanics. Using Direct stiffness method for question $1.$ Please do not share the answer to public I need it privately $!$
