A Grand Entrance You are designing an apparatus to support an actor of mass 80.0 kg who is to "fly" down to the stage during the performance of a play. You attach the actor's harness to a 150 kg sandbag by means of a lightweight steel cable running smoothly over two frictionless pulleys as in figure (a). You need 3.75 m of cable between the harness and the nearest pulley so that the pulley can be hidden behind a curtain. For the apparatus to work successfully, the sandbag must never lift above the floor as the actor swings from above the stage to the floor. Let us call the initial angle that the actor's cable makes with the vertical 0. What is the maximum value ở can have before the sandbag lifts off the floor? (a) An actor uses some dever staging to make s entrance. (b) The free-body diagram for the actor at the bottom of the circular path. (c) The free-body diagram for the sandbag if the normal force from the floor goes to zero. Macor ag Actor Sandbag mactor a SOLUTION Conceptualize…
