The arc of contact between the roll and the workpiece is circular in geometry, and its radius is smaller than the roll radius.

The arc of contact between the roll and the workpiece is circular in geometry, and its radius is smaller than the roll radius. Correct Answer False

The arc of contact between the roll and the workpiece is circular in geometry and its radius is greater than roll radius. This is because of the elastic deformation of roll which increases the contact area.
