High-impact activities are hard on the joints and can cause significant damage to the cartilage in the knees. Peak loads on the knees can be as much as 8 times the person's body weight. If the cartilage in the knee of a 69 kg person has a cross-sectional area of 10.15 cm2, what is the maximum change in thickness of the cartilage, if its unstrained thickness is 4.90 mm?
