A clock pendulum, made of aluminum, has a period of 1.00 s s and is accurate at 8.0°C. If the clock is used in a climate where the temperature averages 36.0°C what correction is necessary at the end of a 40 day period to the time given by the clock?

The time period of the pendulum of the length L is

And so, if the time period for the length at L_1 = L_0 at temperature t_1 = 8 degree C , is T_1 = 1.0 sec,
then the time period at the higher temperature t_2 = 36 degee C, is

Then


And for aluminium, the linear expansion coefficient is given by

And so, the time period at 36 degree C is


So, the correction to 1.0 sec is

So, the correction to 40 day period is

1. You want to design a pendulum for a grandfather clock so that it has a period of 2.00 seconds (so that one “tick” plus one “tock” occur during one complete period). The pendulum has a heavy 8.00-kg bob. (Throughout this problem, assume an ideal simple pendulum: the pendulum’s arm has negligible mass, the bob can be approximated as a point-mass, the initial angle of displacement is small, and there is negligible friction.) a.) If you want the clock to...

A grandfather clock has a pendulum that consists of a thin brass disk of radius 36 cm and mass 1.8 kg that is attached to a long, thin rod of negligible mass. The pendulum swings freely about an axis perpendicular to the rod and through the end of the rod opposite the disk. The pendulum should be designed so that its period is 2 s for small oscillations when the gravitational acceleration is 9.8 m/s2. (a) What should the length...
