Oh, and I would appreciate it if you could tell the answer using computer typing instead of handwriting.

Because I don't know the cursive

If it is difficult, I would appreciate it if you could respond in a convenient way.

    Three rigid bodies (Nodes 2, 3, and 4) are connected by five springs as shown below. Assume that the bodies can only undergo translation in the horizontal direction. Horizontal force P2=1000 N and P4=1500 N is applied to Elements 2 and 4, respectively. The spring constants in (N/mm) are given as: k1=400, k2=500, k3=600, k4=100, and k5=300. Nodes 1 and 5 are fixed. Determine the nodal displacements and reaction forces at the walls. Problem 1. (3 points) Three rigid bodies...
