for an isotropic media you can divide the force on every element in two components.
-bulk component
-rigid component
now bulk component is associated with bulk modulus and other is associated with modulus of rigidity(written as meu).
now bulk component is the one which causes the matter to get compressed and the rigid component only changes the shape of the volume. now, water do not get compressed, it is incompressible and that's why the the force on it is affected by only the rigid component. thats why the modulus of rigidity is zero.
Fluids have the ability to flow and take the shape of their container. They have low shear modulus and can exert pressure in all directions. Additionally, fluids are unable to sustain a shear stress for long periods of time.
The elastic modulus of shale is between 1-70 GPa
The organism that use polysaccharide for strength and rigidity is the plant
Taking the modulus of the wave function allows us to obtain the probability density of finding a particle at a particular position in quantum mechanics. This is because the square of the modulus of the wave function gives us the probability of finding the particle in a given volume element.
The Fineness Modulus (FM) is an index number which is roughly proportional to the average size of the particles in an aggregate sample. It is obtained by adding the cumulative percentages coarser than each of the standard sieves used for segregating sand and dividing the cumulative percentage by 100.
there are different types of modulus it depends on what types of stress is acting on the material if its direct stress then then there is modulus of elasticity,if tis shear stress then its modulus of rigidity and when its volumetric stress it is bulk modulus and so on
modulus of elasticity = 15 Msi; poisson ratio = 0.3 modulus of rigidity = E/ ((2(1 + poisson)) = 5.8 Msi
G = E/2(1+u) where G = mod of rigidity and u =poisson ration and E = young modulus

The modulus of rigidity of a wire is a measure of its resistance to shearing deformation. It is typically represented by the symbol G and is expressed in units of pascals (Pa). The specific value of the modulus of rigidity for a given wire will depend on its material composition and properties.
It is around 40 GPa.
shearing stress to shearing strain
about 70 to 80 GPa
change in shape due to stress applied
It is the ratio of shear stress to shear strain.
