Unformatted text preview: place them on a massless, rigid, circular hoop of radius R . Then, I arrange them so that two of them are on opposite sides of the hoop, and the third is out at some arbitrary angle. If the hoop rotates in its own plane, what is the moment of inertia for the whole system? Answer Selected Answer: 3 m R Question 4 6 out of 6 points In the first part of lab7, suppose you are not told the moment of inertia of the disk. To find the torque applied on the disk, the quantities useful are Answer Selected Answers:...
