To find vertical difflection at 'c' apply dummy force of 1kN=p. vertically towards down

$\underline{Axial \ force \ \bar(N)\ and \ bending \ moment \ \bar(M) \ diagram \ Applying \ C.O.E}$

$\sum m_{A}=0$ enter image description here

$1\times 4M_{A}=0$

$M_{A}=4kN.m$

$\sum F_{y}=0(\uparrow +ve)$

$V_{A}-1=0$

$V_{A}=1kN$

$\sum F_{x}=0(\rightarrow +Ve)$

$\sum F_{x}=0 \ \ \ …
