Point A
Point B
Point C
Point D
A region that starts from upper yield point is called
Elastic region
Hooke's Law region
Plastic region
None of the above
The maximum stress that a material can comprehend before it breaks is called
(a)
What happen to the planes of atoms during upper yield point?
Atom breaks
Atom stay intact
Planes of atoms starts sliding upon each other
None of the above
What are several things would happen if stress acting upon a material exceeding its proportionality limit?
material can retain its length/shape once the force is removed
material cannot retain its length/shape once the force is removed
there would be a permanent set of elongation for the material
material does not obey Hooke's Law
