Referring to the :
RA = RB + 10
Using the compatibility equation
\(\delta_1+\delta_2 = 0\)
\(\frac{{{R_A} \times 1}}{{AE}} + \frac{{\left( {{R_A} - 10} \right) \times 2}}{{AE}} =0 \)
\(\Rightarrow {R_A} = \frac{{20}}{3}\ kN\)
And,
RB = (20/3) - 10 = -10/3 kN
So, the assumed direction for RB is not correct. RB will be in the opposite direction to the assumed direction.
