Question

difine proportinal limit​

Answer 1

Explanation:

• The proportional limit is the maximum stress that a dental material sustains without any deviation, or the magnitude of elastic stress above which plastic deformation occurs. ... So, the proportional limit is defined as the highest stress at which the stress-strain curve is a straight line.

Answer 2

Ello..✌✌

Proportional limit is defined as the point up to which the stress and the strain are directly proportional.
