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?
The spider weighs 6.4*2.5=<<6.4*2.5=16>>16 ounces
So each leg supports a weight of 16/8=<<16/8=2>>2 ounces
That means each leg undergoes a pressure of 2/.5=<<2/.5=4>>4 ounces per square inch
