Support reactions
Hello,
I have had the following question:
Determine the two support reactions at positions ‘A’ and ‘B’ for the following simply supported beam which is acted on by a uniformly distributed load (UDL) and two point loads.
UDL = 1.2K/n
6Kn 3Kn
A  B
2.1m 1.05m 1.05
I have answered it:
(6 x 2.1) + (3 x 3.15) =R2 x 4.2m
(6 x 2.1) + (3 x 3.15) / 4.2 = R2
12.6 + 9.45 / 4.2 = R2
22.05 / 4.2m = R2
5.25kN = R2
R1 9 – 5.25 = 3.75kN
R1= 3.75kN
R2= 5.25kN
Is this correct? Im not sure!
Thanks
Dave
