Which are true 1. a rigid body undergoing planar motion is pinned at the center of mass in the plane of motion; all non-CM points on the rigid body have the same angular velocity. 2. When a rigid body undergoes planar motion the body center of mass remains in a singular plane. 3. The normal force is never perpendicular to the surfaces that applies the normal force. 4. Mass moment of inertia of a rigid body indicates the magnitude of...

Consider the motion of a rigid body with principal moments of inertia I < I<I,, in absence of external forces and torques (i.c., a free rigid body). Assume the body is a rectangular figure of width W, height H and length L (i.e., a book), with H<W<L, as shown in the figure. The angular velocity vector of the rigid body, in the body system, is (, . The conserved energy of the top is E, and the conserved angular momentum...

A Review Learning Goal: To apply the principle of work and energy to a rigid body. Submit Previous Answers Correct Part B The principle of work and energy is used to solve kinetic problems that involve velocities, forces, moments, and displacements. For a rigid body, the principle is Ti + QU1–2 = T2 where Ti is the body's initial kinetic energy, EU1-2 is the work done by external forces and moments that act on the body, and T2 is the...
