For a four$-$span continuous beam with each span $=10ft$ and uniform loading of $1ki\frac{p}{f}t.$

Consider all three load patterns shown on Attachment #$1$ and determine the following:

a$.$ Maximum Support Reaction $($envelope solution$).$ Also, identify its location on the beam.

b$.$ Maximum Shear $($envelope solution$).$ Also, identify its location on the beam.

c$.$ Maximum $+$ ve moment $($envelope solution$).$ Also, identify its location on the beam.

d$.$ Maximum $-$ve moment $($envelope solution$).$ Also, identify its location on the beam.
