If the section modulus of a beam decreases, then bending stress will
For a given stress, the ratio of moment of resistance of a square beam with its sides horizontal, compared to when the diagonal is horizontal is
The moment diagram for a cantilever beam subjected to bending moment at end of beam will be
If the load at free end on a cantilever beam is increased so as to cause rupture, same will occur
Reaction generated at fixed end would be same as end applied load.
Shear force at any point on the beam is the algebraic sum of
Bending moment at any point is equal to the algebraic sum of
The rate of change of shearing force at any section is equal to the rate of
The reaction (in kN) at the support 'A' for the beam shown in the given figure is
A beam carrying a uniformly distributed load rests on two supports ‘b’ apart with equal overhangs ‘a’ at each end. The ratio b/a for zero bending moment at mid-span is
This point is also the point of contra-fiexure and it will be zero at b = 2a.
So, answer is (d).
The point of contra-flexure occurs only in
