Mechanics:
Ring, Chain, Cylinder

PIRA Class: 1Q60.52

Purpose:
Demonstrate rotational instability and how the orientation of an object can change as its rotation increases.

Description:
A ring, a circular section of chain, and a cylinder are each attached to a string that whose end can be inserted into an electric drill and brought up to a fast rotation. The rotation will cause each object to rise up until they are rotating in a horizontal plane (see video).

NOTE: Increase the rotational speed slowly to avoid getting the string tangled in the drill.

Equipment:
Ring, chain, cylinder envelop and electric drill

Location:
Shelf 144 (envelope is in one of the moment of inertia bins), need to purchase an electric drill
