Academics

An elephant that has a mass of 7000 kg evenly distributes her weight on all four feet.

(a) If her feet are approximately circular and each has a diameter of 50 cm, estimate the pressure on each foot.

(b) Compare the answer in part (a) with the pressure on each of the average human male's feet when he is standing up. The weight of the average male is 70 kg. Assume the average male's feet can be treated as rectangles of width 10 cm and length 25 cm.
