Question
The bending moment (BM) along a beam BM = 30x -5x2 kNm where x is the distance in metres from the left hand end.
Find the position and value of the maximum bending moment.
Find the position and value of the maximum bending moment.
Answers
dBM/dx=30-10x=0
x=3m
BM(max)=f(x)=30*3-5(9)=35kNm
x=3m
BM(max)=f(x)=30*3-5(9)=35kNm
