The small block of mass m slides along the radial slot of the disk while the disk rotates in the horizontal plane about its center O. The block is released from rest relative to the disk and moves outward with an increasing velocity r˙ along the slot as the disk turns. Determine the expression in terms of r and r˙ for the torque M that must be applied to the disk to maintain a constant angular velocity w of the disk.
