Question $3$

The bar is supported by a roller constraint at $\backslash ($ B $\backslash ),$ which allows vertical displacement but resists axial load and moment. Determine the reactions at A and B$.$ EI is constant.

Question $4$

For the following systems, state whether determinate or indeterminate $($state degree of indeterminacy$)$ and state whether the systems are stable or unstable.

Question $5$

a$)$ Determine the reactions at the supports $\backslash ($ A$,$ B $\backslash ),$ and $\backslash ($ C$,$ E I $\backslash )$ is constant.

b$)$ Draw the shear and moment diagrams.
