Question

8- The rotational dynamics of a wheel with r=50 cm is investigated using an experimental setup similar to the setup that was used in today?s experiment. The graph below summarizes the results of the experiment. From the data shown, what is the moment of inertia of this wheel? Assume the torque is applied at edge of the disk -10 kg m2 -25 kgm2 -50 kg m2 -100kg m2 9-Assuming that the wheel can be approximated as a uniform disk of radius r=50 cm, estimate the mass of the wheel using the data and your knowledge of rotational inertia. -400 kg -200 kg -100kg -50 kg 10-1f instead we assume that the bulk of the wheel?s mass is concentrated around the outer rim of the wheel and that the wheel can be approximated as a ring of radius r=5Ocm, estimate the mass of the wheel using the data and your knowledge of rotational inertia. -400 kg -200 kg -100 kg 50 kg

Explanation / Answer

Apply torque T = I Alpha

part 8:     25 kgm^2

part 9 : 50 kg

part 10 : 50 kg
