A structure consists of three initially-undeformed springs, as shown in the figure below. Use the following values: k = k = k3 = 5000 lbf/in, P2 1000 lbf, and P4 = 4000 lbf. Solve by hand. 1. Compute all the nodal displacements. = 2. Compute all the forces in the springs and state if the springs are in tension or compression. k k3 mmmm mmm (1) P (2) (3) P Figure 1: Problem 1.
