Problem $4$: A bridge beam has a splice connection at point B which you want to analyze.

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

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

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

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