Final answer:
The statement is true. During a circus act, two performers can swing upside down on a trapeze, with one performer holding the other by the legs.
Explanation:
During a circus act, one performer can swing upside down hanging from a trapeze and hold another performer, also upside down, by the legs. This is a common acrobatic trick performed by skilled circus artists.When a performer holding another upside-down performer by the legs experiences an upward force three times the lower performer's weight, we need to calculate how much the femur bones stretch due to the strain.
Assuming the femurs are modeled as uniform rods, the elongation of these bones under the applied stress can be calculated using the formula ΔL=(F∙L)/(A∙E), where ΔL is the change in length (elongation), F is the force applied, L is the initial length of the bones, A is the cross-sectional area, and E is Young's modulus of the bone material.
