The following statement is not correct regarding the translation of a body: (a) In translation, every line in the body remains parallel to its original position at all time (b) In translation, there is no rotation of any line in the body (c) The velocity of translating body can change in magnitude but not in direction (d) In translation, a point on the body can move on a curve 6. The following statement is incorrect for a rigid body: (a) All lines in its plane of motion have the same angular displacement (b) All lines in its plane of motion have the same angular velocity (c) All lines in its plane of motion have the same angular acceleration (d) All points in its plane of motion have the same linear velocity 7 8 A disk is rotating about an axis parallel to thickness. The line AB perpendicular to the thickness and not intersecting the axis of rotation is undergoing (a) pure translation (c) combined rotation and translation (b) pure rotation (d) oscillation 9. A body in pure translation has (a) no instantaneous center of rotation (b) instantaneous center in the body (c) instantaneous center at infinity (d) two instantaneous centers
