Plastic Section Modulus about the element local y-direction
K(bulk modulus of elasticity)=-{[Pressure x volume]/change in volume}
(Assumes the angle iron isn't constrained on either side.)Where:w = width (parallel to axis)h = height (perpendicular to axis)t = thicknessx = Distance to farthest fiber = h-(t*(2*(h-t)+w) + (h-t)^2 / (2*(w+h-t)))Section Modulus = Moment of Inertia / xSection Modulus = (t*x^3 + w*(h-x)^3 - (w-t)*(h-x-t)^3)/ 3/ xHope that helps
This is a technique used by civil and mechanical engineers to calculate the cross section of a geometric figure. It is used to determine the Yield Moment also called My.
the part of beam which has maximum section modulus should take more load for more strength.
section modulus is a measure of the strength of a beam. The more the section modulus the more is the strength.
section modulus of any section is the ratio of the moment of inertia to the distance of extreem fibre from the neutral axis. plastic section modulus is the section modulus when the cross section is subjected to loading such that the whole section is under yield load. numerically it is equal to the pdoduct of the half the cross section area and the distance of center of gravity of tension and compression area from neutral axis
[Young's Modulus] = M1L-1T-2 __> this is the dimensional formula
In the shear modulus formula, the shear modulus (G) is related to Young's modulus (E) through the equation G E / (2 (1 )), where is Poisson's ratio. This formula shows that the shear modulus is directly proportional to Young's modulus and inversely proportional to Poisson's ratio.

Yes, bending stress is directly proportional to the section modulus. A larger section modulus indicates that the cross-sectional shape of the member is better at resisting bending, leading to lower bending stress. Conversely, a smaller section modulus results in higher bending stress for the same applied bending moment.

In the Poisson's ratio formula, Poisson's ratio is directly related to Young's modulus. The formula is: Poisson's ratio (Lateral Strain / Longitudinal Strain) - (Transverse Stress / Longitudinal Stress) 1 / 2 (Young's Modulus / Shear Modulus). This shows that Poisson's ratio is inversely proportional to Young's modulus.
