Chapter 17, Problem 3 Two disks of the same material are attached to a shaft as shown. Disk A is of radius r and has a thickness b , while disk B is of radius nr and thickness 3 b . A couple M of constant magnitude is applied when the system is at rest and is removed after the system has executed 2 revolutions. Determine the value of n which results in the largest final speed for a point on the rim of disk B .
Chapter 17, Problem 7 Disk A is of constant thickness and is at rest when it is placed in contact with belt BC , which moves with a constant velocity v . Denoting by k the coefficient of kinetic friction between the disk and the belt, derive an expression for the number of revolutions executed by the disk before it attains a constant angular velocity.
