Question

Two friction disks A and B are to be brought into contact without slipping when the angular velocity of disk A is 240 rpm counterclockwise. Disk A starts from rest at time t= 0 and is given a constant angular acceleration with a magnitude a. Disk B starts from rest at time t= 2 s and is given a constant clockwise angular acceleration, also with a magnitude a. Determine (a) the required angular acceleration magnitude a, (b) the time at which the contact occurs.
