PHYSICS FINALS Flashcards
Also known as Normal Stress?
AXIAL STRESS
It is the force perpendicular to the cross-sectional
area?
AXIAL STRESS
It is the force perpendicular to the cross-sectional
area of the member divided by the cross sectional area?
AXIAL STRESS
Units = lb/in^2 or N/m^2?
AXIAL STRESS
The deformation increases in proportion to the force?
HOOKE’S LAW
If the amount of force is
doubled, the amount of deformation is doubled?
HOOKE’S LAW
F = k (deformation), where k is constant depends on material.
HOOKE’S LAW
This is where the F and the ẟ are not proportional?
PLASTIC REGION
This is where the F and the ẟ are not proportional, but rather a small amount of increase in force produces a large amount of deformation.
PLASTIC REGION
The point at which Elastic Region ends?
ELASTIC LIMIT
It is the point at which permanent
deformation occurs?
ELASTIC LIMIT
It is the point at which permanent deformation occurs, if the force is taken off the sample it will not to its original size and shape.
ELASTIC LIMIT
the deformation is no longer directly proportional to the
applied force?
PROPORTIONAL LIMIT
The point at which the deformation is no longer directly proportional to the applied force?
PROPORTIONAL LIMIT
Hooke’s Law no longer holds.
