alleryWhat units does strain carry?
AIt has pascal units
BIt has newton units
CIt has no units
DIt has joule units
Answer & Solution
Correct answer: C. It has no units
1. Strain compares a change in a dimension with that same dimension.
2. Both quantities in that ratio carry the same unit, which cancels.
3. So strain has no units or dimensional formula.
