Comparably low terminal velocity combined with a strong exoskeleton. -Will Quote
bumab Posted June 25, 2005 Report Posted June 25, 2005 F = ma low mass, and low velocity when they hit (relativally) = low force on a strong body Quote
UncleAl Posted June 25, 2005 Report Posted June 25, 2005 Stokes law. Air is viscous for a small objects of low density. That is why goose down gently floats while the same mass of lead as a solid ball falls. Take a strand of dry spaghetti. Break it. Easy! Now try to snap a 1/8" length. Material strength varies as area, r^2; material weight varies as volume, r^3. Small stuff is strong vs. its weight. Quote
