1.6 HOOKE’s LAW
It has been well established that many structural materials up to a certain load level exhibit a direct proportionality of strain with the stress produced in it. This is usually stated as stress is proportional to strain.
Thus, Hooke’s law is defined as the stress induced in a material is proportional to the strain within the elastic limit. This law is applicable both for tension and compression conditions.
This law is valid within certain limits of stress for most ferrous alloys and also with sufficient accuracy to other engineering materials such as timber, concrete and non-ferrous alloys.
