Question
Q5/Draw the bending moment diagram for the beam as shown in the fig.
Expert Solution
Step 1
Let Ra and Rb be reaction forces at End A and B respectively.
Ra + Rb = (2*3) + (1*2) + 3 + 5
Ra + Rb = 16 KN
Taking moment about point A
∑ Ma = 0
Rb *7 = (2*3*1.5) +(1*2*4) +(3*3)+(5*5) = 51
Rb = 51/7 = 7.286 KN
and Ra = 16 - 7.286 = 8.714 KN
