Humpty Dumpty
Given: Spring, Ring Stand, clamps and rods, Meter sticks/rulers, mass hook and masses, Egg (will be provided), Clamp type clothespins or tape (to mark release heights), Clay (to hold egg)
Find: The height from which a mass on a spring must be released in order to just touch the egg without breaking it. Cracking is acceptable, but leakage = fail.
These springs are stiffer than the previous ones we used. When determining the spring constant, you should be able to use up to 1200-1500 grams.
You are not allowed to let any masses fall on the spring until your actual trial. Before you will be given your trial mass, you must show your work for determining the spring constant, including any graphs. Before your actual trial, you must show the work behind your prediction, including LOL charts.
