Elastic Constants by Searle's Dynamical Method 1. Aim To determine Young's modulus \(Y\), modulus of rigidity \(n\), and Poisson's ratio \(\sigma\) of the material of a given wire by Searle's dynamical method using the time periods of oscillation. 2. Apparatus Required Searle's dynamical apparatus, two identical cylindrical bars, experimental wire, rigid supporting stand, stopwatch, screw gauge, vernier calipers, metre scale and physical balance. 3. Theory When an elastic body is deformed within its elastic limit, restoring forces or couples are developed. These restoring actions tend to bring the body back to its original configuration. Searle's dynamical method determines the elastic constants of a wire by observing two independent modes of oscillation of an arrangement containing the wire and two identical bars. The first mode is associated with flexural deformation, while the second mode involves torsional deformation. Th...
