Region	origin	limits	Mu	Mu Hor.	Mu Vert.
AB	A	0-4	$$8x-\frac{2x^2}{2}-20$$	$x-4$	$-2$
BC	C	0-2	$-2x$	$-x$	$-x$

$\begin{align} &\Delta H_C= \int_0^4 (8x-x^2-20)(x-4)\frac{dx}{EI}+\int_0^2 (-2x)(0)\frac{dx}{EI} \\&\phantom{\Delta H_C}=\frac{1}{EI} \int_0^4 \left[8x^2-32x-x^3+4x^2-20x+80\right]dx \\&\phantom{\Delta H_C}=\frac{1}{EI} \int_0^4 \left[-x^3+12x^2-\frac{52x^2}{2}+80\right]dx \\& \Delta …
