Discuss how a grandfather clock (a pendulum clock), accurate at 20oC

Discuss how a grandfather clock (a pendulum clock), accurate at 20^oC,

will run fast or slow on a hot day (say, 30^oC)?

Base your answer on physics and the formula for the simple pendulum.

If you make the rod of the Pendulum out of Wood ( look up the coefficient of linear

expansion) What is the change in length and thus the

period?

Seeing your result, explain how adjustments are made to clocks

running too fast or slow because of temperature change.

Knowing this, what other things in your home, work or life in

general will run differently based on temperature? Does humidity

also have an effect on your example? Explain why? Be creative

and think about things you use all year long that might be affected

by temperature and humidity as far as operation. It does not just

have to be an example that affects timing. It could affect

operation, size, etc.
