The Elastic Cord is supplied in 120cm lengths. Five different diameters are available: 1, 1.5, 2, 2.5 and 3mm. This gives five different values of mass/unit length for those doing investigations involving Melde's experiment.

If you need to know the tension in the cord then you can adopt the setup shown here which uses one of our spring balances (dynamometers). The photograph shows a 2N balance which has a clearly marked scale and is easy to read.
