A disk is free to rotate about an axle at the disk's center. A force of magnitude F is exerted tangentially at the edge of the disk, as shown in the left figure, and the disk has angular acceleration α. The disk is returned to rest and a second identical disk is placed on top of the first disk, as shown in the middle figure. The disks move together and do not slip. A force with magnitude F is again exerted tangentially at the edge of the first disk, as shown in the right figure. A student claims that the angular acceleration will again be α when the force of magnitude F is exerted on the two-disk system. Is the claim correct? Why or why not?
