Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
When a moment is applied at free end of a cantilever it will be transferred by constant magnitude to the fixed end. So, bending moment at any point will be equal to externally applied moment.
∴ Bending Moment at support (Ms) = M
Take moment about fixed end and equate it to zero.
As there is no force, Fixed end moment = Applied moment.
Important Points
In this case bending moment is constant throughout the beam and shear force is zero throughout the beam. It is an example of pure bending.
