Quick Answer: The Set of 3 Elastic Strings is a physics accessory of three stretchable strings for experiments on elasticity, tension, Hooke’s law, vibration and waves. Each string extends under a load and returns to its original length when the load is removed.

Key Features
3 elastic strings, used singly or together for comparison
Lightweight, flexible and easy to handle
Used with spring balances, weights, retort stands, pulleys and wave apparatus
Return to original length when unloaded, within the elastic limit
About This Product
With one end fixed to a stand and a weight or spring balance on the other, students record the force and extension, then repeat with the other strings to compare them. The strings also suit vibration and wave demonstrations and help explain restoring force, stored elastic energy and the elastic limit. They should not be stretched past that limit or released suddenly while stretched.
Frequently Asked Questions
How is Hooke’s law studied with the elastic strings?
Fix one end to a support, hang known weights or pull with a spring balance on the other, measure the extension for each force and compare force with extension.
