37. A clock pendulum made of brass has a period of 0.500 s and is accurate at 20°C. If the clock is used in a climate where the temperature averages 30°C, what correction (approximately) is necessary at the end of 30 days to the time given by the clock? The coefficient of linear expansion for brass is α = 19 X 10-6/°C. Ans. 4.11 min 36 In a hurricane, the air (density 1.2 kg/m3) is blowing over the roof of...
Pendulum Clocks Are Very Important...
1. Pendulum clocks are very important for the history of exploration. Accurate time was the best way to determine one's longitude, since the time of sunrise or sunset depends sensitively on your longitude. In this regard, the great enemy of accuracy was thermal expansion of the pendulum used for the chronometer. We are considering a large mass attached at the end of a brass rod. The mass at the end is much greater than the mass of the rod, so we...
