Question

A light rod is supported horizontally by two wires of the same length L and area of cross -section A but of different moduli of elasticity `Y_(1)andY_(2)` A heavy mass m is suspended at a disance `a_(1)` from the first wire and `a_(2)` from the second wires Find the period of errtical oscillations of the mass.

Answer 1

Correct Answer - `2pi sqrt((m(a_(2)^(2)Y_(2)+a_(1)^(2)Y_(1)))/((a_(1)+a_(2))^(2)Y_(1)Y_(2))(L)/(A))`
