Problem $4(30$ pts$)$ Determine the following if the floor loading is $60$ PSF:

A$.$ What is the tributary area of column A$5?$

B$.$ What it load on column A$5?$

C$.$ If the cross section area of column A$5$ is $20$ sq$.$ in$.$ what is the axial stress in the column?

D$.$ Draw the free body diagram for girder G$1.$ Be sure to provide the magnitude of the loads acting on the girder.

i$)$ Draw the shear and moment diagram for the girder.

ii$)$ Find the maximum shear and moment on G$1.$ With the given cross section of girder G$1$ below, find the maximum shear and bending stress.

Girder G$1$ Cross
