LMEC-4 Apparatus of Shear Modulus and Rotational Moment of Inertia

Short Description:

The ratio of internal stress to strain in elastic limit is an important parameter to measure the deformation of an object under stress. The ratio of normal stress to linear strain is called Young's modulus; the ratio of shear stress to shear strain is called shear elastic modulus, or shear modulus for short. Young's modulus and shear modulus are widely used in engineering design and selection of mechanical materials in machinery, construction, transportation, medical treatment, communication and other industrial fields.
