What Is modulus of rigidity? Explain |
| Answer» Modulus is a constant of elasticity given by Hooke\'s Law, which says stress is directly proportional to strain, within the elastic limit.Modulus of rigidity is one among three elastic constants. It\'s associated with change in shape of the body.Like every modulus it\'s too equivalent to the ratio of stress and strain. But as per definition, since it\'s the modulus of change in shape, therefore, it\'s precisely expressed by the ratio of shearing stress and shearing strain.We know shearing stress is F÷A and shearing strain is theta ( I would like to consider it β) | |
