A grandfather clock contains a pendulum of lenghth 0.99336 m with a weight of 1.4kg. The driving mechanism comprises anohter mass of 2kg which goes down by 0.8m in 7 days in order to keep the amplitude of oscillation of the pendulum to give theta=0.08(<<1). What is the natural period of the pendulum? What is the value of Q for this system? Take the gravitational acceleration equal to 9.80665m/s^2?(adsbygoogle = window.adsbygoogle || []).push({});

For the period part of the question, I simply assumed that this was a simple pendulum and used the equation T=2pi*sqrt(l/g) where l is the length of the pendulum (ie 0.99336). Can someone please check if this is right :shy:
