$2)$ FEM $(70\backslash \%)$

Given the following beam system:

a$)$ How many degrees of freedom are there assuming one finite element per member?

b$)$ What are the constraints degrees of freedom

c$)$ b$)$ Write the global load vector

d$)$ Write the assembled global stiffness matrix for the system including the spring of stiffness $\backslash ($ K $\backslash ),$ and the torsional spring of stiffness $\backslash ($ K$\_\{$s$\}\backslash ).$ Use only one finite element per beam.

e$)$ What is the reaction force at the torsional spring?
