Week 7 “A Grandfather’s Clock”

Each week, you will reply to two discussion forum questions. You may submit your answers together or separately – just be sure you address both questions. Here are your questions for this week:

Part 1

Will a grandfather clock (a pendulum clock), accurate at 20^oC, run fast or slow on a hot day (say, 30^oC)? Explain.

Part 2

Why do roads sometimes buckle in the hot summer heat? What are some ways engineers who build bridges work to avoid this?
