A giant spider is discovered. It weighs 2.5 times the previous largest spider, which weighed 6.4 ounces. Each of its legs has a cross-sectional area of .5 square inches. How much pressure in ounces per square inch does each leg undergo? Think carefully first, then make a decision:
The spider weighs 6.4 * 2.5 = 16 ounces. So each leg supports a weight of 16 / 8 = 2 ounces. That means each leg undergoes a pressure of 2 / .5 = 4 ounces per square inch. So, the answer is 4.
