a material on whome the strees through mg is increassed
the redion the material regain shope and hooks law is valid
the region where the material regain its shape hooks law not valid
the region the material do not regain its shape
the point where breaking starts
if you move past it and then decrease the mg still the strinf is goint to break
region where a small change is strain brings too much stress

ENERGY ANYLISIS WHEN STRESS IS APPLYED TO THE MATERISAL
formula and defivation :question:
as when you solve the problems it would be observed that not all the energy goes in teh potential energy but some of it is lost is raising the temprature of the body heat problems can be asked on it
THERMAL EXPANCTION
when bodye are heated the particle vibrate
the viblation causes the increase in the distance in berweeen them

AREAL EXPANCTION :question:
VOLUMETRIC EXPANCTION :question:
PROBLEMS WHEN ALFA IS CHANGING WITH TEMPRATURE
PROBLEMS ON RINGS AND CAVITY
BIMETALIC STRIP
SCALE PROBLEMS :
WATER CONTAINER PROBLEMS :question:
formula when only scale is expanding :question:
