| modulus of elasticity in shear [`mäj·ǝ·lǝs ǝv i´las`tis·ǝd·ē in `shir] MECHANICS A measure of a material's resistance to shearing stress, equal to the shearing stress divided by the resultant angle of deformation expressed in radians. Also known as coefficient of rigidity; modulus of rigidity; rigidity modulus; shear modulus. |
