When SF is zero What is the bending moment?
In case of simply supported beam, bending moment will be zero at supports. And it will be maximum (positive or negative) where shear force is zero.
What is the unit of bending moment?
It is therefore clear that a point of zero bending moment within a beam is a point of contraflexure—that is, the point of transition from hogging to sagging or vice versa. Moments and torques are measured as a force multiplied by a distance so they have as unit newton-metres (N·m), or pound-foot (lb·ft).
What is point load example?
A point load is a force that is applied to a concentrated point on the support. An example would be a person standing at the free end of a diving board.
When bending moment is maximum SF is?
Bending moment is maximum where shear force is zero or its changes sign (positive to negative or vice-versa).
When SF is zero the bending moment is Mcq?
Explanation: The maximum bending moment occurs in a beam, when the shear force at that section is zero or changes the sign because at point of contra flexure the bending moment is zero. Explanation: The positive bending moment in a section is considered because it causes convexity downwards.
What is a bending load?
bend·ing load·ing. (bending lōding) Distortion of an object by a force (e.g., a load placed on a beam located between two supports may cause the beam to curve).
When does the maximum oonding moment occur under a beam?
The maximum oonding moment produced by moving concentrated loads occurs under one of the loads when that load is as far from one support as the center of gravity ol alllhe moving loads on the beam Is from the other support.

What is the formula for load per unit length?
w= load per unit length, lbs./in. Δ = deflection or deformation, in. x= horizontal distance from reaction to point on beam, in. List of Figures
