Question

Name 3. Gymnast. A gymnast holds onto a single bar with both hands with her arms outstretched as shown to the right. She swings around the bar in a full circle. Assume the only forces acting on her are gravity and a normal force between the bar and her hands. The gymnasts mass is 35 kg and the distance from her outstretched hands to her feet is 2.5 m. A. What is the torque on the gymnasts body around the axis of the bar when her body is perfectly horizontal? Assume her center of mass is halfway from the bar to her feet. Express your answer as a magnitude, in kg m/s. (3 pts) B. What are the two orientations of the gymnasts body, expressed as angles (in degrees) relative to the acceleration of gravity vector, where she is in equilibrium? (2 pts) State what type of equilibrium (stable, unstable, or neutral) each of these two orientations has. (2 pts) (continued ov F13A

    The outstretched hands and arms of a figure skater preparing for a spin can be considered a slender rod pivoting about an axis through its center ( Ibar = 1 12 mℓ2 where ℓ is the length of the bar ). When the skater's hands and arms are brought in and wrapped around their body to execute the spin, the hands and arms can be considered a thin-walled hollow cylinder. The hands and arms have a combined mass 10 kg....

    Many aspects of a gymnast's motion can be modeled by representing the gymnast by four segments consisting of arms, torso (including the head), thighs, and lower legs, as in the figure below. Figures a and b describe a gymnast's motion as he swings about a bar. A side-view of the gymnast as he swings about the bar. The gymnast's back is horizontal, his arms are vertical, his thighs are at an angle of 60° to the horizontal, and his lower...

    On average, both arms and hands together account for 13% of a person's mass, while the head is 7.0% and the trunk and legs account for 80%. We can model a spinning skater with her arms outstretched as a vertical cylinder (head, trunk, and legs) with two solid uniform rods (arms and hands) extended horizontally. Suppose a 70.0 kg skater is 1.80 m tall, has arms that are each 64.0 cm long (including the hands), and a trunk that can...
