A frame shown below is designed to support a triangular load with a

maximum magnitude of $Wk\frac{N}{m}(W$ and $P$ same values as per Force

method question$)$ and $PkN$ acting on the middle span as shown in the

figure below. This beam is pinned at all ends except $B$ which is

continuous. The length of member $AB$ is $L,H$ are $=3\mathrm{.}7m.$ El is constant

for all spans.

Please use slope and deflection method to calculate the theta values and

the moments using the equations. SFD$,$ BMD is not required for this

question.

Input the value of moment MBC in the box below $($without signs and

units, just the number with decimals$)$:
