TORQUE 2. A 45 kg Boulder needed to be moved. A pipe, with a mass of 20 kg and a total length of 400 cm, was used to lift the rock. If a person was to have a fulcrum 3 m from the end of the pipe, what torque would be needed to move the Boulder? CENTER OF MASS 3. A 1-meter stick has a mass of 50 grams. Where would you place your nger to balance the ruler if 50 gram masses are placed at 15 cm, 55 cm, 60 cm, and 95 cm? ROTATIONAL EQUILIBRIUM 4. Determine the tension in the support cable. Mass of Beam = 18 kg Mass of each Cylinders = 5 kg Length of Beam = 1.6 m Distances from left: Fulcrum = .7 m Cable = 0.2 m Cylinder: 0.5 m and 1.5 m Cylinder Cylinder Cable
