1. A rotational damping mechanism, comprising:
a housing;
a rotating member;
a spring arm assembly including a first spring arm,
wherein the spring arm assembly is coupled to the rotating member and configured to rotate in response to a rotation of the rotating member,
wherein the first spring arm extends radially outward of the spring arm assembly toward the housing in response to the rotation of the rotating member, and
wherein the rotation of the rotating member is damped in response to extending the first spring arm due to a friction brake force caused by extending the first spring arm and an eddy current brake force caused by extending the first spring arm.
