BIO 105 Lecture Notes - Lecture 7: Cochlea
Document Summary
Insects can hover and fly backwards i: forewing and hind wing can lock together during flight, the insect wing, veins serve to stiffen the wing, cells contain the wing material, the wing is not shaped like airfoil, how do insects generate lift, motion of the wings, leading edge moved down and forward, wing flipped leading edge toward rear, moved up and backward, wing flipped again, wings push against air and produce lift iii. Human flying machine: why can"t individual humans fly like birds or insects, humans are just too heavy, what about pterosaurs, were very large and heavy but they fly, wingspan 9 to 20 ft, flap of skin was the wing surface off of the pinkie finger", modified skin tissue to form the rays to support the wing, more likely to use soaring as means of flight, two solutions around weight problem, small wing area, lots of thrust, large wing area, little thrust.
