Question

The unit of strain is

A. kg m-³
В. Ра
C. Nm-²
D. none​

Answer 1

Answer:

D. none

Explanation:

microstrain

The unit for strain in the SI (Système International) is “one” i.e. 1 ε= 1 = 1 m/m. In practice, the “unit” for strain is called “strain” and the symbol e is used. Usually, strain is in the order of um/m, i.e. 10-6, and therefore, the unit “µε” (microstrain) is most commonly used.

Answer 2

Answer:

Option D) is the correct answer.

Explanation:

The strain unit is dimensionless. It is the ratio between the length shift and the initial length, so it is unitless.
