1. Use direct stiffness method and solve in terms of P and k

a) Find the global stiffness matrix [K]

b) Apply a point load P at node 3 pointing rightward, and determine the displacements at nodes 2, 3, and 4 also the reactions at nodes 1 and 5.

2. Use the portal method to determine the approximate vertical reactions. Circles represent pinned connections. Note the pins on the horizontal beam are just to the right/left of the columns.
