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
