What is the unit of stress?
KPa
N/m
Pa/s
mm²/N
Hooke's Law states that:
Stress ∝ Strain
Stress ∝ Load
Stress ∝ Elastic Limit
Stress = Constant
The point beyond which a material does not return to its original shape is called:
Yield Point
Ultimate Point
Elastic Limit
Breaking Point
Which is NOT a type of stress?
Tensile
Compressive
Shear
Plastic
In stress-strain curve of mild steel, the yield point occurs:
Before elastic limit
After elastic limit
At fracture point
At ultimate stress
Which relation between elastic constants is correct?
E = 2G(1+μ)
G = 3K(1-2μ)
K = E/3(1+μ)
E = G + K
Thermal stress occurs when:
