The purpose of this problem is to give you a feel for the magnitude of reynolds number appropriate to real airplanes in actual flight. a. consider a dc-3 s. the wing root chord length (distance from the front to the back of the wing where the wing joins the fuselage) is 14.25 ft. consider the dc-3 flying at 200 miles per hour at sea level. calculate the reynolds number for the flow over the wing root chord. (this is an important number, because as we will see later, it governs the skin-friction drag over that portion of the wing.)b. consider a f-22. the chord length where the wing joins the center body is 21.5 ft. consider the airplane making a high-speed pass at a velocity of 1320 ft/s at sea level (mach 1.2). calculate the reynolds number at the wing root.

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?
