1. For the spring assemblage shown in Figure P2–2, determine the displacement at node 2 and the…


1. For the rise substantiality shown in Figure P2–2, designate the demolition at node 2 and the securitys in each rise part. Also designate the security F3. Given: Node 3 displaces an equality d = 1 in. in the positive x order owing of the security F3 and k1 = k2 = 500 lb/in.

2. a. For the rise substantiality shown in Figure P2–3, obtain the global inelegance matrix by straightforward superposition.

b. If nodes 1 and 5 are urban and a security P is applied at node 3, designate the nodal demolitions.

c. Designate the reactions at the urban nodes 1 and 5.
