Assignment $9$

I have the same three shelves with some books on them.

For the first two shelves, draw the:

Shear diagram

Moment diagram

Approximate deflected shape

Indicate with a $\text{'}$C$\text{'}$ or a $\text{'}$T$\text{'}$ above and below the beam, which sides of the beam are in tension and compression

For the shear and moment diagrams, please label all locations where there is a maximum, minimum or change in the diagram

Please also indicate where on the beam these changes occur, e$.$g$.,$ with the distance to the end labelled.

EXTRA CREDIT: Shelf $3$ is for extra credit. For this one, please now consider the $7$ books as a uniform distributed load instead of as one equivalent point load, as we have looked at it before in A$8$ and A$9$
