Problem 1
You are allowed to use the Matlab scripts
for this problem
Consider the spring assemblage shown in the
figure below with spring stiffness
$k_1$ = 100 lb/in., $k_2$ = 200 lb/in., and
$k_3$ = 100 lb/in. A force P = 150 lb acts on node
4.
Submit the following results,
(a) the global stiffness matrix $[K]$,
(b) the displacements of nodes 3 and 4,
(c) the reaction forces at nodes 1 and 2,
(d) the spring forces, and
(e) a copy of your main Matlab script.
[Partial answer for checking your work:
$u_3$ = 0.6 in.]
Develop a Matlab program to analyze the
spring assemblage using the finite element
method.
