Tensile stress	Compressive stress
1] When the resistance offered by a section of member is against an increase in length, the section is said to offer a tensile stress.	1] When the resistance offered by a section of member is against an decrease in length the section is said to offer a compressive stress.
2] Intensity of tensile stress is $P = \frac{P}{A}$	2] Intensity of compressive stress is $P = \frac{P}{A}$
3] The corresponding strain is called tensile strain. $ Tensile \ strain = \frac{Increase \ in \ length}{Original \ length}$	3] The corresponding strain is called compressive strain. $ Compressive \ strain = \frac{Decrease \ in \ length}{Original \ length}$
