This lateral shrinkage constitutes a transverse strain that is equal to the change in the width divided by the original width. (1) As Bulk Stress = Force Area.. (2) The dimension formula of force = MLT (3) It relates the deformation produced in a material with the stress required to produce it. This tells us that the relation between the longitudinal strain and the stress that causes it is linear. . Now the formula for young's modulus or the modulus of elasticity is: As we know, strain is a dimensionless quantity, because it is a change in dimension divided by the original dimension, whereas stress has the same dimensions as pressure. This is only because it tells us about the ability of the body to be able to resist deformation on the application of force. We can then use a linear regression on the points inside this linear region to quickly obtain Young's modulus from the stress-strain graph. Therefore, Young's modulus has the same dimensions that stress has. Thus Youngs modulus may be expressed mathematically as. If it has balanced forces, then it is completely still.
