Which type of beam, freely supported at two points, has one or both ends extending beyond these supports?
Overhang beam
An overhang beam is supported at two points, similar to a simply supported beam. The defining characteristic of the overhang beam is the portion of the beam that extends past these support points, which can significantly affect the bending moment and shear force distribution along the beam.
Important Questions from Shear Force and Bending Moment
For a simply supported beam of length L with a triangular load that varies gradually (linearly) from zero at both ends to w per unit length at the centre, the maximum bending moment is
For simply supported beams, the bending moment at supports (or ends) is always
A cantilever of length L carries a gradually (linearly) varying load from zero at its free end to w per unit length at the fixed end. The product of deflection and flexural rigidity at the free end is
If the shear force at a section of a simply supported beam is zero, the bending moment at the section is
Shear force at any point of the beam is the algebraic sum of
