In a third worksheet, create features identical to the features created on the two prior worksheets

for the beam subjected to loadings shown in Figure $3$ below. Utilize the principle of superposition

to generate the results table and plots.

Please solve using superposition so I can find the value of Ra and Rb$.$

L $=280$ in$,$ P $=400$ lb$,$ a $=120$ in$,$ w $=18$ lb$/$in
