Steel:  The below figure shows the stress/strain diagram of a piece of steel that has been subject to a tensile load.  There are a number of significant points/regions that have been identified (points 1-6).   Place the following items in the correct order (such that they correctly correlate with points 1-6 on the diagram). Actual Rupture stress Yield Point Nominal rupture stress Commencement of strain hardening Ultimate Tensile Stress Start of Necking

What is the largest value of stress on the Stress-Strain Diagram called?*

Which point on the stress strain curve occurs after the ultimate point?*1 pointa) Last pointd) Material limitb) Breaking pointc) Elastic limit

hat is the point P shown in the stress-strain curve?*1 pointd) Breaking pointb) Elastic limita) Lower yield pointc) Proportionality limit

For a steel sheet with k = 500 MPa, ε0= 0.05, n = 0.30, the true strain at necking would be ___________ if tensile necking begins at the maximum load. Choose the best from the choices. (a) 0.25 (b) 0.30 (c) 0.2 (d) 0.15

What is the stress-strain curve?*1 pointb) It is the relationship between stress and straina) It is the percentage of stress and stainc) It is the difference between stress and strain
