Question

are the dimensions of elasticity the dimensions of stress/the dimensions of strain? help.. i got [M^1L^−1T^−2] is that right..?

Answer 1

I'm not really sure what units you're using here (M, L, T ?), but the units of the modulus of elasticity (Young's modulus) should be the same as the stress. The equation is
\[E = \frac{\sigma}{\epsilon} \]
where the strain, \(\epsilon\), is dimensionless. (Strain is generally the amount of deformation divided by the original length of the material. The units of deformation and original length should be the same, and so should cancel out.)

Hope it helps.
