Final answer:
Shear strain is not a dimensionless angular quantity; it is actually a measure of the deformation caused by shear stress.
Step-by-step explanation:
Shear strain is a dimensionless angular quantity.
False. Shear strain is not a dimensionless angular quantity; it is actually a measure of the deformation caused by shear stress. Strain is given as a fractional change in shape or geometry under different types of stress. In the case of shear stress, shear strain is the change in shape or deformation caused by parallel forces acting tangentially to the surface. It is not angular, but rather a measure of displacement or deformation.
