TENSILE TEST DATA

REQUIREMENTS

Convert the graph obtained from the tensile test machine to stressstrain curve:

In the tension test, test specimen of a circular cross$-$section with diameter $=0\mathrm{.}55in.(13\mathrm{.}8mm)$ and gage length of $2in.(50\mathrm{.}8mm)$ will be loaded gradually until rupture $($complete failure$).$

From curve stress$-$strain find:

a$.$ Proportional limit$.$

b$.$ Upper Yield point.

c$.$ Lower Yield point

d$.$ Ultimate stress.

e$.$ fracture stress.

f$.$ Modulus of resilience.

g$.$ Modulus of toughness.
