Q: The stress at which extension of a material takes place more quickly as compared to the increase in load, is called as
  • A. Elastic point
  • B. Plastic point
  • C. Breaking point
  • D. Yielding point
Correct Answer: Option D - Yielding point– The stress at which extension of a material takes place more quickly as compared to the increase in load, is called yielding point. Elastic point– Elastic limit marks the partial break down of elasticity beyond which removal of load result in a degree of permanent deformation.
