Dynamics and Torques WCLN.ca 1 1. Let's attempt to simulate Arnold's feat of strength by setting up a simulation as shown below. Be Dynamics and Torques sure to click on Balance Lab at the bottom of the screen to enable you to select masses and test for equilibrium. WCLN.ca 15. Describe the ideal position and "stance" that would enable the man to hold the woman with the Examine to two diagrams below. You may assume that the "pivot" point (about which the least amount of effort (force). Be sure to reference how his center of mass location can be torques are calculated) for the diagram of the left is the man's front (right) foot. moved. Where should it be ideally? How should he arrange his arms? Again, make references For each diagram, label all of the forces acting and clearly label the pivot. Remember, to torque, gravitational forces are always drawn at the object's center of mass location. Part 2: Mastery Find an appropriate point in the clip to analyze. Make sure it is a time when Arnold is dangling the man with one arm only. Create a screen shot of this event and use it to make estimates as to the location of Arnold's center of mass, along with any other appropriate distances (refer to questions 1 1 and 12 in Core above). Use the diagram below for Arnold's basic "dimensions: Note: Arnold's actual mass is 2351b. 12. Compare the two diagrams above. On the simulation what represents 58 m a. the man? b. the woman? c. the front foot of the man? d. the man's arms? 13. Back to the simulation: Click on the Ruler on the right-hand side. Remove the 10kg mass and w 881 replace it with a 5kg mass. What must change in order for the two sides to balance? Justify your answer using the torque equation. 14. Replace the 5kg with the 10kg mass. Move the 20kg mass one step forward. What must change in order for the two sides to balance? Justify your answer using the torque equation.
