Question

find the relation between the tensile strength and stress with numerical values

Answer 1

The tensile strength of a material is the maximum amount of tensile stress that it can take before failure, for example breaking.
The stress applied to a material is the force per unit area applied to the material. The maximum stress a material can stand before it breaks is called the breaking stress or ultimate tensile stress
steel high tensile = 1650 mpa(yield), 1860mpa(ultimate)
