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...
For one interpretation of curl, consider the vector velocity of any point P of a rigid body in motion. Let Vo be the velocity of a point O of the body, o the angular velocity of the body with respect to point O, and F the vector from O to P. Find the curl of the vector at point P, that is of the vector V,-, +or·Give an interpretation of your result. 1.
QUESTION 5 If you have a rigid body with a plane motion, D'Alembert's principle is applied to prove that the external forces acting on a rigid body are equivalent to a vector ma attached to the mass center. o True False
