Two lightweight rods 24centimeter in length are mounted perpendicular to an axle and at 180 degree to each other. At the end of each rod is a 480-gram mass. The rods are spaced 42 centimeter apart along the axle. The axle rotates at 4.1rad/s.
Find the component of the total angular momentum along the axle?
Find angle does the vector angular momentum make with the axle? [Hint: Remember that the vector angular momentum must be calculated about the same point for both masses, which could be the cm.]
