Q: In a tension test on mild steel on UTM (universal testing machine), at which stage of the test should the extensometer be removed from the test specimen for its safety?
  • A. Ultimate stress point
  • B. Limit of proportionality point
  • C. Yield point
  • D. Rupture point
Correct Answer: Option C - Universal Testing Machine (UTM) :- • It is a machine that is used to perform standard tensile and compressive tests on materials, components and structure. It can be used to tensile test, compressive test and shear test. • A tension test on mild steel on UTM, the test should be extensometer be removed from the test specimen for its safety for yield point.
