Question $2(40$ points$)$

A frame with a distributed load is

shown in Figure $2.$ Each member has

the same solid circular cross$-$section

$($ r$=12$mm $)$ and is made from the

same material $($ E$=200$GPa $).$

Develop a global stiffness matrix for

this system, represented in the global

coordinate system. Additionally,

calculate all nodal displacements and

reactions forces.

Note that node $1$ is fixed, while node $2$

is pinned.
