Define Young's modulus and modulus of rigidity. Give their expressions and units. What is meant by elastic limit and angle of shear? What is the unit of candela? What is the SI unit of work? What is the Elastic modulus of steel ?
Elastic modulus is a general term for the ratio of stress to strain in materials, while Young's modulus specifically measures this ratio for linear elastic deformation under tension or compression.
Learn what Young's modulus means in science and engineering, find out how to calculate it, and see example values.

One definition of a fluid is a substance with a shear modulus of zero. Any force deforms its surface. Shear Modulus Equation The shear modulus is determined by measuring the deformation of a solid from applying a force parallel to one surface of a solid, while an opposing force acts on it...

In the elastic region, there is a linear relationship between stress and strain, which is known as “Young’s modulus” or the “modulus of longitudinal elasticity” and is generally expressed as “E.” Once Young’s modulus (the modulus of longitudinal elasticity) is known, you can ...
whereEis the Young modulus. For incompressible fluids (i.e.K\rightarrow+\infty) the Poisson ratio tends to\nu=0.5. It is common, for incompressible flows, to use\nuinstead ofKin order to be able to express this limit situation. On the other hand,\nu=0.5may lead to several numerical is...
This alloy has been commonly used as a base metal for MMCs reinforced with a variety of fibres, particles and whiskers. Tungsten carbide (WC) is approximately two times stiffer than steel, with a Young's modulus of approximately 550GPa, and is much denser than steel or titanium. 189 Words...
