I need solution for $15$ & $14$

A beam is simply support at the ends and is continuous over two spans. The left$-$hand span is

$16$ ft and the right$-$hand span is $20$ ft $.$ The beam supports a uniform load of $900$ plf$,$ which in$-$

cludes its own weight, over the entire $36$ ft and also a concentrated load of $10,000lb$ applied at a

point that is $5$ ft from the left$-$hand end of the beam. Determine the bending moment at the in$-$

termediate support due to the uniform load only.

A$.-38,600ft-lb$

B$.-37,800ft-lb$

C$.-36,500ft-lb$

D$.-35,200ft-lb$

For the beam described in Question $13,$ determine the bending moment at the intermediate sup$-$

port due to the concentrated load only.

A$.-18,264ft-lb$

B$.-12,086ft-lb$

C$.-11,874ft-lb$

D$.-10,026ft-lb$

If the concentrated load on the beam described in Question $13$ is reduced to $8000$ lb $,$ the total

bending moment at the intermediate support due to the uniform load and the concentrated load

is equal to $-45,820ft-lb$ and the reaction at the left$-$hand support is

A$.10,936lb.$

B$.9836$ lb $.$

C$.8914$ lb $.$

D$.8116$ lb $.$
