DTorsion

Answer:

A. Sagging

Read Explanation:

Positive bending moment is also known as sagging. When a simply supported beam is subjected to UDL, the bending moment will be positive. Sagging occurs when the upper layer of the beam experiences compressive stresses and the bottom layer experiences tensile stresses. Hogging, on the other hand, is negative bending moment where top fibres of the beam experience tension and the bottom layer experiences compression. Points of contra flexure are points of zero bending moment where the beam changes its curvature from hogging to sagging.

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

When the shear force at a section of a beam under bending is zero, the bending moment at that section is either a maximum or a minimum. This is because the shear force is a measure of the rate of change of the bending moment. When the shear force is zero, the bending moment is either at its peak or at its trough.

For a simple case of a simply supported beam experiencing a point load at its center, which of the following equilibrium conditions hold?At any point on the beam:

The algebraic sum of the moments due to all forces acting on the beam is zero
The algebraic sum of vertical forces acting on the beam is zero
The algebraic sum of horizontal forces is always negative (less than zero)
The total acceleration experienced by the beam is zero

Which of the following beams is likely to have the point of contraflexure?

The reaction at the two supports of a simply supported beam carrying a uniformly distributed load over its entire span is: (the intensity of loading on the beam is w/unit length and I is the length of the beam).
