A ruler is on a pivot through its center. Pitt i The ruler is at test when a student briefly exerts a downward tone on the tight end. \"I The magnitude of the force exerted by U} the student is equal to half the weight of the ruler. After the student stops pushing. the ruler spins clockwise at a constant rate. (Assume the pivot is z 't'ctt'onless.) ' l-lnnd pushes (with force Ruler spins clockwise at a us! to half the rulers onsumt rate I. In the space below. draw :1 free-body ight) c diagram for the ruler at each of the instants shown. Recall that your diagram should include: - a description of each forte. - the name of the object on which each force is exerted. and - the name of the object exerting each force. Free-body diagram for ruler Free-body diagram for ntler while hand is pushing while spinning at constant rate 2. For the instant shown above while the hand is pushing. rank the magnitudes ofthe forces that appear on your free-body diagram. (List the torces from largest to smallest. If two forces are equal in magnitude, indicate that explicitly.) Explain. 3. For the instant shown above while the ruler is spinning at a constant rate. rank the magnimdes of the forces that appear on your heecbody diagram. (List the forces from largest to smallest. If two forces are equal in magnitude. indicate that explicitly.) Explain. A picture of the ruler at the two instants is reproduced below.
