alleryDimensions of strain:
AMLT
BM
CDimensionless (ratio of lengths ΔL/L)
DT
Answer & Solution
Correct answer: C. Dimensionless (ratio of lengths ΔL/L)
Strain = (ΔL)/L = (change in length)/(original length).
Both same dimension, cancel out. Dimensionless.
Same for shear strain (angle, in radians).
