1. Support reaction calculation

$\begin{align} &\sum M_C=0\ (\circlearrowright +ve) \\& H_A\times2+10\times4=0 \\& H_A=-20\ kN \\& \boxed{H_A=20\ kN} \ (\leftarrow) \\ \\& \sum F_Y=0\ (\uparrow+ve) \\& V_C-10=0 \\& \boxed{V_C=10\ kN}\ \\ \\& \sum F_X=0\ (\rightarrow+ve) \\& -20+H_C=0 \\& \boxed{H_C=20\ kN} \end{align}$
