In a tensile test, near the elastic limit zone ____________
A. Tensile stress increases in linear proportion to the stress
B. Tensile stress increases at a faster rate
C. Tensile stress decreases at a faster rate
D. None of the mentioned
Answer:C
In a tensile test, near the elastic limit zone ____________
A. Tensile stress increases in linear proportion to the stress B. Tensile stress increases at a faster rate C. Tensile stress decreases at a faster rate D. None of the mentioned
Explanation: The stress first decreases and then decreases before the strain hardening occurs. The decreases in the stress is due to the attraction between carbon molecules.
