Problem 29PE

a circus act, one performer swings upside down hanging from a trapeze holding another, also upside-down, performer by the legs. If the upward force on the lower performer is three times her weight, how much do the bones (the femurs) in her upper legs stretch? You may assume each is equivalent to a uniform rod 35.0 cm long and 1.80 cm in radius. Her mass is 60.0 kg.

Step-by-Step Solution:

Step-by-step solution Step 1 of 5 Euler’s equation can be used to calculate the elongation in the bones. Is found fro the young’s modulus is he elongation is young’s modulus is force is the area is the initial length Step 2 of 5 The radius of the leg The cross sectional area of the leg Step 3 of 5 The mass of a performer The total force acting on the legs is,
