Strain is reported as a fractional change in length, volume or geometry. That makes strain:
AMeasured in newtons
BA negative quantity
CMeasured in pascals
DA dimensionless number
Answer & Solution
Correct answer: D. A dimensionless number
1. A fraction divides like by like.
2. The units cancel out.
3. It is a dimensionless number.
