Resumen de A Modification to Maxwell's Needle Apparatus
Maxwell's needle apparatus is used to determine the shear modulus (η) of the material of a wire of uniform cylindrical cross section. Conventionally, a single observation is taken for each observable, and the value of η is calculated in a single shot. A modification to the above apparatus is made by varying one of the observables, namely the mass of the hollow cylinder (m h). With this modification five sets of values of mass difference (m s − m h) are taken and corresponding values of difference of the squares of time periods (T2 2 − T1 2) are plotted on the graph for calculating the value of η.
