The stress experimented by the bungee cord due to Max's weight is approximately 299.680 kilopascals.

<h3>How to find the stress experimented by the bungee cord</h3>

Let suppose that the stress (\sigma), in pascals, experimented by the bungee cord is entirely <em>elastic </em>and <em>uniform</em>. By Newton's Laws we know that the tension (T), in newtons, experimented by the cord equals Max's weight. The stress on the bungee cord is axial and is described by following formula:

\sigma = \frac{m\cdot g}{\frac{\pi\cdot D^{2}}{4} }   (1)

Where:

  • m - Max's mass, in kilograms
  • g - Gravitational acceleration, in meters per square second
  • D - Diameter of the circular cross section, in meters

If we know that m = 15\,kg, g = 9.807\,\frac{m}{s^{2}} and D = 0.025\,m, then the stress experimented by the bungee cord is:

\sigma = \frac{(15\,kg)\cdot \left(9.807\,\frac{m}{s^{2}} \right)}{\frac{\pi}{4}\cdot (0.025\,m)^{2} }

\sigma \approx 299679.845\,Pa\, (299.680\,kPa)

The stress experimented by the bungee cord due to Max's weight is approximately 299.680 kilopascals. \blacksquare
