Measure properties of an elastic cord
Investigate the properties of an elastic cord as it
supports different amounts of weight.
- Set things up so that a piece of cord of
initial length Lo is hanging freely from a rod.
Make the initial length at least 40 cm.
Measure the diameter of the cord using calipers.
- Hang at least six different masses in the range 300 g to 700 g
from the cord. For each mass, measure the amount
Δ L by which the cord stretches.
- Make a neat table with your results.
