Question

- 3- Determine the reactions on the beam shown. Assume A is a pin and the support at B is a roller (smooth surface). 10KN m BA 3m 4m am A न

Answer 1

Here we convert uniformly varied load to the point load:

— У, ХТоо ҳ4 200 KN В с Е 244 * */"> во к— 2m RA

Total Moment @ A = 0

ΜΑ = 0

RB *6 = 200 * (4/3+2)

$R_B*6=200*(10/3)$

$R_A=200-R_B$

$R_A=200-111.112$

So reaction at A is 88.888 kN while on B is 111.112 kN.
