Young's modulus is determined experimentally by applying tensile strain (pulling on the ends) to a number of samples of the material under investigation and plotting the strain versus the elongation and taking the slope of the central part of the plot.
Yes, indeed. Sometimes tensile modulus is different from flexural modulus, especially for composites. But tensile modulus and elastic modulus and Young's modulus are equivalent terms.
The elastic modulus, also called Young's modulus, is identical to the tensile modulus. It relates stress to strain when loaded in tension.
Hookes law says that stress, s, is proportional to strain,e, as s = E e where E is modulus. Since strain has no units (it is deflection per unit length) the units of E are the same as s. E is the slope of the stress strain diagram.
Young's modulus
The modulus of elasticity is the slope of the linear portion of the curve (the elastic region).
what we now call just the "slope" was once called the "modulus of slope", the word "modulus" being used in its sense of "number used to measure" (as in "Young's modulus").
M refers to the modulus of the slope.
m stands for "modulus".
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.
Is the modulus, gradient or slope of the line.
m stands for modulus, and is a measure of the slope.
Modulus.
1. slope" was once called the "modulus of slope", the word "modulus" being used in its sense of "number used to measure" 2. It is originated from the Arabic word MOMAS means tangant.1.
m stands for "modulus of slope"; modulus means "number used to measure." We now call the slope just simply "slope" but still use "m" to indicate it in the formula.
This question probably is referring to a 2% secant modulus, which can be the tensile, flexural or compressive modulus (slope of a stress/strain curve) of a material that is determined from calculating the slope of a line drawn from the origin to 2% strain on a stress/Strain curve.
It is not documented why the letter m was chosen for slope. However, mathematician John Conway suggested that m could mean 'modulus of slope'.
