Problem $2$: A bridge beam has a connection at point $C$ which you want to analyze. For the beam below and moving truck load:

a$)$ Draw the influence line with ordinate values for the internal shear at point $C.$

b$)$ Draw the influence line with ordinate values for the internal moment at point $C.$

c$)$ Determine the absolute maximum shear $($V$)$ at point C due to the moving load.

d$)$ Determine the absolute maximum moment $(M)$ at point C due to the moving load.
