The tensile test curve of the steel tensile test bar is shown in the figure. a-)What are the approximate hardness values of the steel? b-)How much tensile force is applied to break this test rod? c-)What was the initial measuring length of \( 51 \mathrm{~mm} \) in the broken rod?
Expert Answer
Answer:- a) In case of steel, the Ultimate Tensile Strength is empirically related with the Brinell Hardness Number as follows: UTS(psi)=5
