Which one of the following is an accurate statement?
A) The ratio of tensile stress to tensile strain is called Young's modulus.
B) "Strain" has a meaning very close to "force."
C) "Stress" has a meaning very close to "stretch."
D) Tensile stress is measured in newtons.
E) Tensile strain is measured in meters.

Question

Quizplus · Accepted Answer

Young's modulus is defined as the ratio of the tensile stress applied to a material to the resulting tensile strain along the same axis. Therefore, statement A is an accurate statement. B, C, D, and E are incorrect. Strain is the measure of the deformation or elongation of a material, while force is a measure of the strength or intensity of an interaction between objects. Stress is the measure of the internal forces within a material, while stretch is a measure of the elongation or expansion of an object. Tensile stress is measured in pascals, while tensile strain is a ratio or a dimensionless quantity.
