(l-a) While the apparatus is at rest, apply a downward (-Y direction) force to the le_ft end of the rod. (1-b) While the apparatus is at rest, apply an upward (+Y direction) force to the le_ft end of the rod. (1-c) While the apparatus is at rest, apply a downward (-Y direction) force to the rim end of the rod. [1-d) While the apparatus is at rest, apply an upward (+Y direction) force to the rim end of the rod. (2-a) Hold the left end of the rod and rotate the disk so that the to]; edge of the disk is moving in the 41 direction. Then release the rod. Relative to the pivot, what is the direction of the Torque exerted by the force? Relative to the pivot, what is the direction of the Torque exerted by the force? Relative to the pivot, what is the direction of the Torque exerted by the force? Relative to the pivot, what is the direction of the Torque exerted by the force? What is the direction of the angular momentum of the disk? What is the direction of the angular velocity of the disk? (2-b) Hold the left end of the rod and rotate the disk so that the to]; edge of the disk is moving in the *Z_ direction. Then release the rod. (3-a) While the disk is rotating as in (E), hang a mass from the left end of the rod. What is the direction of the angular momentum of the disk? What is the direction of the angular velocity of the disk? Describe what happens to the motion of the gyroscope relative to the pivot. [3-b) While the disk is rotating as in l2-b !, hang a mass from the left end of the rod. (4-a) Repeat the set up in (3- a): spin the disk quickly and then spin it slowly. Describe what happens to the motion of the gyroscope relative to the pivot. How does the angular speed of the disk affect the motion of the gyroscope around the pivot as observed in (3-a)? [4-b) Repeat the set up in (3- b): spin the disk quickly and then spin it slowly. How does the angular speed of the disk affect the motion of the gyroscope around the pivot as observed in (3-b)
