A Cantilever beam of Span 3m carries two point loads Of 10 kN and 20kN are acting at Om and 2m From free End. Draw SFD AND BMD

Q.A Cantilever beam of Span 3m carries two point loads Of 10 kN and 20kN are acting at Om and 2m From free End. Draw SFD AND BMD

SOLUTION:

Total load = 30 + 10 = 30kn

SFD

F{A} = 30kn( same upto AC)

FC =( Just left of c) = 30KN

FC = (Just right of c) = 10 KN (Same upto CB)

FB = (just left of B) = 10KN

FB = (Just right of B) = 0 kn

BMD

MB = O

ML = – 10 * 2 = – 20 KNm

MA = -10×3-20×1 = -50 kn

max BM occurs at A = – 50 KNm
