Unformatted text preview: Chapt. 13 Equilibrium and Elasticity Multiple-Choice Problems 013 qmult 00100 1 1 3 easy memory: rotational equilibrium 1. To be in rotational equilibrium, an object must have: a) zero angular momentum. b) non-zero angular momentum. c) constant angular momentum. d) non-constant angular momentum. e) no hair. 013 qmult 00200 2 5 3 moderate thinking: static equilibrium 2. In STATIC equilibrium: a) there is no translational or rotational acceleration, but there can be NONZERO velocity and angular velocity. b) there is no translational or rotational acceleration, and NO translational or rotational velocity. If static equilibrium exists in a specific reference frame, it exists in ALL reference frames no matter how those reference frames may be moving. c) there is no translational or rotational acceleration, and NO translational or rotational velocity. If static equilibrium exists in a specific reference frame, it exists ONLY in reference frames NOT moving with respect to the specific reference frame system.moving with respect to the specific reference frame system....
