It was stated that three factors that influence spreading in rolling are (a) the width-to thickness ratio of the strip, (b) friction, and (c) the ratio of the radius of the roll to the thickness of the strip. Explain how each of these factors affects spreading.

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
