Question

8.1.2 Observe and explain Two objects of equal mass but different mass distribution that are attached to a pulley system are initially at rest, as shown in the illustration. Strings pull down on the objects, exerting a force of the same magnitude on the axles. The rate of rotation of object 2 increases more rapidly than that of object 1. Fill in the table that follows. 92014 Pearson Education. cey Zajicek (mzaj2760@students Kleinisd.net) on 2/8/2018 from 99 68.43.0 authorized to use unsl S represents a copynight violation.

Explanation / Answer

The figure of 1st question is missing.

For later questions we know that the body having larger moment of inertia is difficult to rotate.

The body in which particles are farther from the axis will have large MOI.

So for 8.1.3 (a), the figure above which has all balls on the same side of axis is difficult to rotate.

And for 8.1.3 (b), the ring will be difficult to rotate.
