Max (mass = 15 kg) is hanging from one end of a 13-m long bungee cord that has its other end fixed to a bridge above. The bungee

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. $\blacksquare$

What is the probability that a randomly chosen u. S. President is left-handed and a democrat?.

sashaice [31]

Using conditional probability, it is found that there is a 0.052 = 5.2% probability that a randomly chosen U. S. President is left-handed and a democrat.

<h3>What is Conditional Probability?</h3>

Conditional probability is the probability of one event happening, considering a previous event. The formula is:

$P(B|A) = \frac{P(A \cap B)}{P(A)}$
