Structural Mechanics 4 Shear Force, Bending Moment and Deflection of Beams
20 kN RA RB 3.00m 2.00m

Sum of moments about RA = 0
20 x (2.00) - RB x ( ) = 0 RB x (5.00) = 20 x (2.00) RB = 20 x (2.00) / (5.00) RB = 8.00 kN

Sum of moments about RB = 0
RA x ( ) x (3.00) = 0 RA x (5.00) = 20 x (3.00) RA = 20 x (3.00) / (5.00) RA = kN

So likely that calculations are correct!
CHECK VERTICAL FORCES UPWARD REACTION = RB + RA = = 20 kN DOWNWARD FORCE = 20 kN So likely that calculations are correct!
