Question

Define Rigidity modulus of Elasticity?Give it units and dimension.​

Answer 1

Answer:

Modulus of rigidity is the ratio of shear stress to the shear strain

$Modulus \: = \frac{Stress}{Strain}$

Strain is dimensionless, where as Stress has the dimensions of Pressure.

$M {L}^{ - 1} {T}^{ - 2}$

Answer 2

Hey hii...

Modulus of rigidity is also know an shear.when we applied tangential force to. The Any of the end.from that end body displace some angle.

Si unit Newton per meter square.or Pascal

Dimension = MLT-2/M square

Hope it will helpful...
