[Young's Modulus] = M1L-1T-2 __> this is the dimensional formula
Modulus of elasticity will be 2.06*10^5 N/mm2
A good number to use is 30,000,000 psi (207 GPa)
there are different types of modulus it depends on what types of stress is acting on the material if its direct stress then then there is modulus of elasticity,if tis shear stress then its modulus of rigidity and when its volumetric stress it is bulk modulus and so on
Young Modulus is the slope of the stress-strain diagram in the linear elastic region. This is the most common use of modulus. As the material goes non-linear in the stress strain curve, thre slope will get increasingly lower. In this case one connects the end points of the stress strain diagram at the point of interest with a straight line. The slope of that straight line is the secant modulus.
pi x d3 / 32
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.

Torssional section module
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.
