Modulus of Rigidity: ► Definition of Modulus of Rigidity: Modulus of Rigidity (or Shear Modulus) is the coefficient of elasticity for a shearing force. It is defined as “The ratio of shear stress to the displacement per unit sample length (shear strain)" Modulus of Rigidity can be experimentally determined from the slope of a stress- strain curve created during tensile tests conducted on a sample of the material. ► Formula: The formula of modulus of rigidity of metallic rod is given as h = 360 × M × g × L × R л² × r 4 × (q 2 - q 1 ) ► Unit: The unit of Modulus of rigidity in C.G.S system is dyne/cm². Circumference of a Circle: ► Definition of Circumference: “The perimeter of a circle is called the circumference .” The circumference is the distance around the circle. The circumference, C , of a circle is given by the formula C = 2лr where r is the radius of the circle, and Radius: The name comes from Latin radius , meaning "ray" but also the spoke of a chariot wheel. The plural in English is radii (as in Latin), but radiuses can be used, though it rarely is.
