### One end of a uniform rigid bar of mass ( m ) is connected to a wall by a hinge joint ( O ), and the other end carries a concentrated mass ( M ), as shown in the figure. The bar rotates about the hinge point ( O ) against a torsional spring and a torsional damper. It is proposed to use this mechanism, in conjunction with a mechanical counter, to
