Select all true statements below:

A correct Moment equation could be:

$M_{R1}=0=-8k({20}^{\text{'}})-6k({10}^{\text{'}})+R_2({30}^{\text{'}})$

Symetric loading so $R_1=R_2=7k$

$R_1$ and $R_2$ will both be forces in the

positive $Y$ direction.

A correct equilibrium equation could

be:

$F_x=0$
