Concept explainers

Free Body Diagram

The system of forces acting on a body tends to either rotate it or make the body undergo motion. In general, when an external agent exerts a force on a body, the body undergoes translational motion and rotational motion. The body has six degrees of freedom under the influence of that force. Here, three degrees of freedom are from the translational motion while the other three are from the rotation motion. However, sometimes the bodies are not allowed to undergo any motion and are fixed, under such conditions the body is said to be constrained.

Question

9-d12
The figure shows a tabletop experi-
ment that can be used to determine an unknown
moment of inertia. A rotating platform of radius
R has a string wrapped around it. The string is
threaded over a pulley and down to a hanging
weight of mass m. The mass is released from
rest, and its downward acceleration a (a > 0) is
measured. Find the total moment of inertia I of
the platform plus the object sitting on top of it.
(The moment of inertia of the object itself can
then be found by subtracting the value for the
empty platform.)
