1. A) What is the formula for engineering stress (σ)?
The engineering stress is a measure of the internal forces distribution within a solid material in response to an applied external load.
The formula for engineering stress (σ) is σ=F/A0.
The original cross-sectional area of the material is used in the calculation, even if the material undergoes deformation and the actual area changes during the test.
a) 1 and 2 are correct.
b) 2 and 3 are correct.
c) 1 and 3 are correct.
