Therefore, the reaction at support A is 2100 N and the support reaction at B is 1950 N.
Calculate the point load due to uniform varying load in section AC i.e. W1
W1=AC*(600N/m)
=3m*(600N/m)
=1800N
Calculate the point load due to uniform varying load in section AC i.e. W2.
W2=1/2*AC*(900-600n/M)
=450N
Calculate the point load due to uniformly distributed load in section CB i.e. W.
W=CB*(600N/m)
w=1800N
Use the condition of force equilibrium in the vertical direction.
W1+AP+W2*AQ+W*AR-Rb*AB=0
2700N.m+900N.m+8100N.m-Rb*6m=0
Rb=1950N
Ra+1950N=4050N
Ra=4050N-1950N
support reaction is Ra=2100N
