What Are The Objectives of Testing (3)
To Provide Design Data
To Assist With Material Selection
To Ensure That A Material Conforms To A Standard
What Are The Requirements of Testing Method (2)
What Are The Different Building Standards (4)
BSI - British Standards Institution
ASTM - American Society for Testing Materials
ISO - International Standards Organisation
CEN - European Standards Committee
What Are The Two Mechanical Testing Classifications
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
The Gradient on The Tensile Test Graph Is...
Young;s Modulus - Stiffness.
What Is Proof Stress
Stress That Will Produce A Given Plastic Strain In The Material.
Used In The Same Way As Yield Stress
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)
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.
How do we calculate stress
force (n/mm2) divide cross sectional area
force (n/mm2) divide cross sectional area... is the calculation for
what is the basic si unit for stress
