Problems $2-58$ to $2-69$

Use Figure P$2-58$ for all problems. For the given data in the probe ment and data you read from the indicated stress$-$strain curve, the following properties of the material:

a$.$ Yield strength. State whether the yield point is used to detof this value or if the $0\mathrm{.}2\%$ offset method is used.

b$.$ Ultimate tensile strength.

c$.$ Proportional limit$.$

d$.$ Elastic limit$.$

e$.$ Modulus of elasticity for the range of stress in which Hookidi. applies.

f$.$ Percent elongation. $($The gage length for each test is $2\mathrm{.}00$ in $.)$

g$.$ State whether the material is ductile or brittle.

h$.$ Examine the results and judge the kind of metal used to deter the test data.

i$.$ Compare your results and find a particular alloy from App Tables A$-10$ through A$-14$ that has similar properties.
