A physical pendulum shown in Fig. is made up of a rod 60 cm long with mass 0.50 kg and a disk of 3.0 cm radius with mass 0.60 kg. Find the period of this pendulum. |

Answer» `I=(1)/(3)m_(1)l^(2)+(1)/(2)m_(2)r^(2)+m_(2)(l+r)^(2)` The distance between the centre of mass and the axis is `a=(1//2m_(1)l+m_(2)(l+r))/(m_(1)+m_(2))` Hence we find the period. |
