Use Figure $1$ problems for problem $17.$ For the given data in the problem statement and data you read from the indicated stress$-$

strain curve, determine the following properties of the material:

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

used.

b$.$ Ultimate tensile strength.

C$.$ Proportional limit$.$

C$.$ Elastic limit$.$

C$.$ Modulus of clasticity for the range of stress in which Hooke's law applies.

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

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

$1..$ Examine the results and judge the kind of metal used to determine the test data.

Compare your results and find a particular alloy from alloy from Appendix tables $A-10$ through $A-14$ that has

similar properties in vour textbooks pages $782-787.$

Use Curve $B$ from Figure $1.$ Final length between gage marks $=2\mathrm{.}3$ in$.$
