Question

State the units and dimensions of modulus of elasticity.

Answer 1

modulus elasticity= stress/strain
unit N/m^2
ML^-1 T^-2

Answer 2

Hey mate,

◆ Modulus of elasticity-
Modulus of elasticity is the ratio of stress to strain.
E = stress/strain

◆ Unit of modulus of elasticity-
As strain is a unitless quantity, modulus of elasticity has same units as of stress or pressure. i.e. Newton/Sq.meter (N/m^2).
This is also called as Pascal (Pa).

◆ Dimensions of modulus of elasticity-
As strain is a dimensionless quantity, modulus of elasticity has same dimensions as of stress or pressure. i.e. [ML^-1T^-2]

Hope that is useful...
