Rigid Body

A rigid body is an object which does not change its shape or undergo any significant deformation due to an external force or movement. Mathematically speaking, the distance between any two points inside the body doesn't change in any situation.

Rigid Body Dynamics

Rigid bodies are defined as inelastic shapes with negligible deformation, giving them an unchanging center of mass. It is also generally assumed that the mass of a rigid body is uniformly distributed. This property of rigid bodies comes in handy when we deal with concepts like momentum, angular momentum, force and torque. The study of these properties – viz., force, torque, momentum, and angular momentum – of a rigid body, is collectively known as rigid body dynamics (RBD).

Question

sidered is motion sickness. Studies have shown that the negative effects
of motion sickness begin to appear when the rotational motion is faster
than two revolutions per minute. On the other hand, the magnitude of the
centripetal acceleration at the astronauts' feet should equal the magnitude
of the acceleration due to gravity on earth. Thus, to eliminate the diffi-
culties with motion sickness, designers must choose the distance between
the astronauts' feet and the axis about which the space station rotates to
be greater than a certain minimum value. What is this minimum value?
