The ratio of tensile stress to tensile strain is called:
Correct answer: C. Young's Modulus
- A. Modulus of elasticity
- B. Bulk Modulus
- C. Young's Modulus
- D. Shear Modulus
Explanation
Young's modulus is a measure of the stiffness of a material. It is defined as the ratio of tensile stress to tensile strain within the elastic limit of a material. In other words, Young's modulus is the ratio of the applied stress to the resulting strain, within the elastic limit of the material.Young's modulus is denoted by the symbol "E" and has the unit of Pascals (Pa) or Newtons per square meter (N/m²). It is a measure of how much a material will stretch (i.e. its elongation) under a given load. The higher the value of Young's modulus, the stiffer the material is.
