Hooke’s Law and Young’s Modulus

Hooke’s Law and Young’s Modulus Hooke’s Law About 350 years ago, a scientist named Robert Hooke discovered that the extension of a material is proportional to the stretching force provided that the material is not permanently stretched. This is now known as Hooke’s law. According to Hooke’s law, doubling the force doubles the extension, trebling the force trebles the extension, and so…

Stress and Strain (Engineering Science)

Stress and Strain (Engineering Science) Stress Stress is the internal resistance which the body offers against a load or an external force. There various types of stresses classified as follows : Simple or direct stress – this includes tension, compression and shear. Indirect stress – this includes bending and torsion. Combined stress – a combination of direct and indirect stress. Simple…
