How do you solve problem? I'm confused about which equations to use and which variables go where. How should I think about what is going on? You have a pulley 14.6 cm in diameter and with a mass of 1.9 kg. You get to wondering whether the pulley is uniform. That is, is the mass evenly distributed, or is it concentrated toward the center or the rim? To find out, you hang the pulley on a hook, wrap a string around it several times, and suspend your 1.2 kg physics book 1.5 m above the floor. With your stopwatch, you can find that it takes 0.62 s for your book to hit the floor. Use g=9.8 m/s2. a) What is the moment of inertia if the pulley is uniform? b) What is the actual moment of inertia of the pulley based on your measurement? c) Is the pulley uniform (within 1% of uniform), is the mass of the pulley concentrated toward the center, or is the mass concentrated toward the rim?
13 Which is INCORRECT among the following statements? The counterpart of torque in translational motion is force. The counterpart of work in translational motion is mass. Dynamics for rotational motion is analogous to translational dynamics None of the above
A fulcrum supports a uniform meter stick as shown. The center of mass of the meter stick is at its middle. Use the rule or rules you developed earlier to predict the mass of the meter stick in the following two experimental illustrations. In each picture, the available objects cause the meter stick to be balanced.
