Problem $2$

The compound beam shown in Figure $2$ is subjected to a uniform dead load of $1\mathrm{.}5k\frac{N}{m}$ and a single live load of $10$ kN $.$ Determine $($a$)$ the maximum negative moment created by these loads at A$,$ and $($b$)$ the maximum positive shear at B$.$ Assume A is a fixed support, B is a hinge, and C is a roller. Find the required influence lines using the method of sections as discussed in class.
