This formula uses 4 Variables
Variables Used
Moment of Inertia of Weld about Neutral Axis - (Measured in Meter⁴) - Moment of Inertia of Weld about Neutral Axis is defined as the quantitative measure of the rotational inertia of the body about the neutral axis.
Bending moment in welded joint - (Measured in Newton Meter) - Bending moment in welded joint is the reaction induced in a structural element when an external force or moment is applied to the element, causing the element to bend.
Distance of Point in Weld to Neutral Axis - (Measured in Meter) - Distance of Point in Weld to Neutral Axis is defined as the distance of any point in the Weld to the neutral axis.
Bending stress in welded joint - (Measured in Pascal) - Bending stress in welded joint is the normal stress that is induced at a point in a welded joint subjected to loads that cause it to bend.
STEP 1: Convert Input(s) to Base Unit
Bending moment in welded joint: 985000 Newton Millimeter --> 985 Newton Meter (Check conversion here)
Distance of Point in Weld to Neutral Axis: 200 Millimeter --> 0.2 Meter (Check conversion here)
Bending stress in welded joint: 130 Newton per Square Millimeter --> 130000000 Pascal (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
