Destructive
Non Destructive

5

On The Tensile Test Graph, What Are The Various Values

A - Elastic Limit
AO - Hooke's Law, Stress Is Proportional To Strain.
Y - Yield Stress
U - Ultimate Tensile Stress

6

The Gradient on The Tensile Test Graph Is...

Young;s Modulus - Stiffness.

7

What Is Proof Stress

Stress That Will Produce A Given Plastic Strain In The Material.

Used In The Same Way As Yield Stress

8

How do we calculate the cross sectional area

diameter divided by 2 to get the radius. radius squared (times by it's self) x 3.14 (PII)

9

diameter divided by 2 to get the radius. radius squared (times by it's self) x 3.14 (PII)... is the equation for

calculating the cross sectional area.
