ROTATIONAL EQUILIBRIUM 1. Figure 9.5 is a pictorial representation of a uniform meter stick with a 100-g object suspended from it at the 30-cm mark and a 200-g object suspended from it at the 80-cm mark. The meter stick is placed horizontally on a fulcrum at its 50-cm mark. 0 30 50 80 100 g Figure 9.5 200 g a. Is the meter stick in rotational equilibrium? Show enough of your work to support your answer. b. If the meter stick is not in rotational equilibrium, in which direction will it rotate? 2.

PRE-LAB ROTATIONAL EQUILIBRIUM 1. Figure 9.6 is a pictorial representation of a uniform meter stick with a 100-g object suspended from it at the 30-cm mark and a 200-g object suspended from it at the 80-cm mark. The meter stick is placed horizontally on a fulcrum at its 50-cm mark. a. Is the meter stick in rotational equilibrium? Show enough of your work to support your answer. b. If the meter stick is not in rotational equilibrium, in which direction will it rotate?

The Torque Balance Three masses are attached to a uniform meter stick, as shown in Figure 12.9. The mass of the meter stick is 150.0 g and the masses to the left of the fulcrum are m1 = 50.0 g and m2 = 75.0 g. Find the mass m3 that balances the system when it is attached at the right end of the stick, and the normal reaction force at the fulcrum when the system is balanced. Figure 12.9 In a torque balance, a horizontal beam is supported at a fulcrum (indicated by S) and masses are attached to both sides of the fulcrum. The system is in static equilibrium when the beam does not rotate. It is balanced when the beam remains level.
