The modulus of elasticity , E, relates tensile stress to tensile strain
The modulus of rigidity, G, relates shear stress to shear strain
The bulk modulus, K, relates compressive stress to volume strain
The three are related using u, poisson ratio of material, that varies generally from 0 to 0.5
E = 9K/ (1 + 3K/G)
G = E/2(1+u)
G = 3(1-2u)K/2(1+u)

Can young modulus of elasticity equals modulus of rigidity?
For isotropic materials G = E/ (2(1+u) where u = poisson ratio
Briefly explain another method to determine modulus of rigidity?
By using tensile test.
What is modulus rigidity of nylon?
It will depend on the Nylon type; average is about 200,000 psi (1380 MPa)
Dimensional formula of modulus of rigidity?
y(young's modulus of rigidity)=stress/strain now strain is dimensionless hence y=stress y=M L-1 T-2
What is the types of modulus of elasticity?
1. Young's modulus of elasticity, E, also called elastic modulus in tension 2. Flexural modulus, usually the same as the elastic modulus for uniform isotropic materials 3. Shear modulus, also known as modulus of rigidity, G ; G = E/2/(1 + u) for isotropic materials, where u = poisson ratio 4. Dynamic modulus 5. Storage modulus 6. Bulk modulus The first three are most commonly used; the last three are for more specialized use
What are the different types of modulus elasticity?
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
What is the Modulus rigidity for steel?
modulus of elasticity = 15 Msi; poisson ratio = 0.3 modulus of rigidity = E/ ((2(1 + poisson)) = 5.8 Msi
Relation between youngs modulus and modulus of rigidity and poisson's ratio?
G = E/2(1+u) where G = mod of rigidity and u =poisson ration and E = young modulus

What is the value of the modulus of rigidity of the wire?
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.
What is the linked between modulus of elasticity and modulus of rigidity?
It is around 40 GPa.
What is the ratio of modulus of rigidity?
shearing stress to shearing strain
What is the modulus of rigidity of spring steel?
about 70 to 80 GPa
What is torsional rigidity of a shaft?
It is defined as ratio of the product of modulus of rigidity and polar moment of inertia to the length of the shaft. Torsional Rigidity is caluclated as: Torsional Rigidity= C J/l
Modulus of rigidity is the ratio of?
It is the ratio of shear stress to shear strain.
Where the couple produced in the barton's apparatus to find out modulus of rigidity?
flywheel
How do you find Modulus of rigidity using graph?
