(l-a) While the apparatus is at rest, apply a downward (-Y direction) force to the t end of the rod. Relative to the pivot, the direction of the exerted by the force? (1-b) While the apparatus is at rest, apply an upward (+Y direction) force to the t end of the rod. Relative to the pivot, the direction of the exerted by the force? (l-c) While the apparatus is at rest, apply a downward (Y direction) force to the m end of the rod. what is Torque Relative to the pivot, the direction of the exerted by the force? (l-d) While the apparatus is at rest, apply an upward (+Y direction) force to the m end of the rod. what is Torque Relative to the pivot, the direction of the exerted by the force? (2-a) Hold the left end of the rod and rotate the disk so that the tgp edge of the disk is moving in the +_Z direction. Then release the rod. 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 t2}; edge of the disk is moving in the g direction. Then release the rod. What is the direction of the angular momentum of the disk? What is the direction of the angular velocity of the disk? (3-a) While the disk is rotating as in 241, hang a mass from the left end of the rod. Describe what happens to the motion of the gyroscope relative to the pivot. (3-b) While the disk is rotating as in 12-b1, 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)
