Practice Questions

Question 1

What gauge length requirement differentiates ASTM E8 from E8M for most round tensile specimens?

Question 2

In microhardness testing, the hardness number (kgf/mm^2) is defined as the applied test force divided by which quantity?

Question 3

Which ASTM standard specifies the microindentation hardness test method for materials?

Question 4

Which specialized mechanical test evaluates material behavior at high strain rates by using stress pulse propagation?

Question 5

A Vickers microhardness test applies a $P=500\,\mathrm{gf}$ load and yields an indentation diagonal $d=30\,\mu\mathrm{m}$. Calculate $HV$ using $HV = 1.854\,\dfrac{P}{d^2}$. Which is closest?
