Conclusion
The elastic behaviour of bungee cord was found to be non-linear for varying applied loads apart from in the range of 2 to 6 N.
At applied loads ranging from 2 to 6 N, the spring constant was found to remain constant at approximately 908 ±0.027 N/m. At loads above and below this range, the spring constant was higher, and the spring-mass system was therefore stiffer.
For an applied mass of 250 g, the measured natural frequency (0.97 ±0.084 Hz) was found to be in good agreement (and within the predicted errors) when compared with the natural frequency predicted using the equation for a spring-mass system with the calculated spring constant (0.96 Hz).
