During a circus act one performer swings upside down hanging from the trapeze while holding another performer, also upside down by the calves. The legs (femurs) of the lower performer undergo deformation due to the upward force from the upper performer. A) If the upward force on the lower performers legs is 3 mg (three times her weight) How much do the bones in her upper legs stretch and meters? You may assume each bone is equivalent to a uniform rod 31 cm long and 1.75 cm in radius and the legs are massless, serving only to transmit the upward force on the torso. Her mass is 59 kg in Young’s modulus for tension is 1.6x10^10 N/m^2

Explanation:

Missing Details. Most models can't incorporate all the details of complex natural phenomena. 

Most Are Approximations. Most models include some approximations as a convenient way to describe something
