Young's modulus measurement was provided by exclusively using the instruments on electronic basis, including micrometer, calliper and weight. Ohtsuki [9] defined a new measuring method of Young's modulus for flexible materials, based on a large bending deformation of specimen subjected to axial compressive forces at both fixed ends.

The Theory Before we move ahead, do you know what a Searle's apparatus is? Searle's apparatus consists of two metal frames F1 and F2. Each frame has a torsion head at the upper side and a hook at the lower side.

Upload your study docs or become a young module is a material property that determines its rigidity and elasticity. the experiment consists of two long straight threads of the same length and equal radius, suspended side by side by side by a fixed rigid support. an elastic module of = and 400 gpa d is also within the range of values reported for cementite particles [29, 30.] in … To determine the rigidity modulus of the material of a given cylindrical rod through telescope and scale method. Apparatus: Searle's static torsion apparatus: rod with attached pulley, weight hanger, slotted weights, telescope, mirror and scale. Shear modulus, or rigidity modulus n is defined as the ratio of stress F/A to strain Δx/l when In the Searle's method to determine the Young's modulus of a wire, a steel wire of length 1 5 6 c m and diameter 0. 0 5 4 c m is taken as experimental wire. The average increase in length for 1. 5 k g w t is found to be 0. 0 5 0 c m. Then the Young's modulus of the wire is Fig. E 9.1: Searle's apparatus for determination of Y A IM To deter mine Y oung's modulus of the material of a given wir e by using Searle's apparatus. A PPARATUS AND MATERIAL REQUIRED Searle's apparatus, slotted weights, experimental wire, screw gauge and spirit level. SEARLE'S APP ARATUS It consists of two metal frames P and Q hinged The previously mentioned exception to the assumption of small deformation is a method of Young's modulus determination originally due to Searle, which is described by Tyler (1961b) and by Worsnop and Flint (1961b). In this method a wire undergoes bending vibrations but at any instant it is bent into a circular arc. Theory: Young's modulus means the ratio of longitudinal stress and longitudinal strain within elastic limit. It is denoted by Y. If
