Choose an option
-
ATrue
-
BFalse
-
CTrue only for ductile materials
-
DFalse unless temperature is constant
Answer
Correct Answer: True
Explanation
ConceptAxial loads that push ends together reduce length and create compressive normal stress (σ < 0 by sign convention) and compressive strain.
Final AnswerTrue
