# Quick Answer: How To Draw Bending Moment Diagram?

## What is bending stress formula?

The bending stress is computed for the rail by the equation Sb = Mc/I, where Sb is the bending stress in pounds per square inch, M is the maximum bending moment in pound-inches, I is the moment of inertia of the rail in (inches)4, and c is the distance in inches from the base of rail to its neutral axis.

## What is the formula of bending moment?

Calculate BM: M = Fr (Perpendicular to the force) Bending moment is a torque applied to each side of the beam if it was cut in two – anywhere along its length.

## What is SFD and BMD?

SFD and BMD: The shear force diagram ( SFD ) and bending moment. diagram( BMD ) of a beam shows the variation of shear. force and bending moment along the length of the beam.

## What is SF and BM diagram?

SF & BM DIAGRAM In Shear force diagram and bending moment diagram, the positions of important points of beam are plotted along X axis and respective values of shear forces and bending moments at that points are plotted along Y axis. A line is then drawn joining these points of Y co-ordinates to get the diagram.

Shear Force & Bending Moment Diagram of Simply Supported Beam

1. Draw shear force and bending moment diagram of simply supported beam carrying point load.
2. Both of the reactions will be equal.
3. R1 = R2 = W/2 = 1000 kg.
4. When simply supported beam is carrying point loads.
5. Shear force between (B – C) = S.F (B -C) = 1000 – 2000.

## What is the unit of bending moment?

Explanation: Moment is a product of force and perpendicular distance and the bending moment is the algebraic sum of moments taken away from the left or the right of the section hence the SI units of bending moment is same as the moment i.e kNm.

## What is deflection formula?

Generally, deflection can be calculated by taking the double integral of the Bending Moment Equation, M(x) divided by EI (Young’s Modulus x Moment of Inertia).

## How do you calculate bend?

K = K-factor, which is t / T. T = material thickness. t = distance from inside face to the neutral line. A = bend angle in degrees (the angle through which the material is bent ) Bend allowance.

Angle 90
K-factor 0.33
Thickness 10
Bend allowance 20.89

## What is a real life example of bending?

For example, a closet rod sagging under the weight of clothes on clothes hangers is an example of a beam experiencing bending.
