A 158 lb man runs on a wet surface at 3 mph before decelerating to 1.5 mph about 4 feet before a right turn. While attempting to make the turn he slips and his body weight shifts onto his right side which results in a fractured lower right fibula and ankle. Let’s assume that the fractural load level for this person to sustain a foot-ankle fracture is 11 N. The injury resulted in a closed, spiral fracture.

(1) List and estimate the forces involved.

(2) Also list the force involved when compared to the injury tolerance.
