A potter forms a piece of clay into a cylinder. As he rolls it, the length, L, of the cylinder increases and the radius, r, decreases. If the length of the cylinder is increasing by 0.9 cm per second, find the rate at which the radius is changing when the radius is 3 cm and the length is 11 cm. (Give units)

1) 25pt)Poiseuille’s Law is a fundamental law of fluid dynamics that describes the flow velocity of a viscous incompressible fluid in a cylinder. It says that in a cylinder of radius R and length L, the velocity of the fluid r (where r ≤ R) units from the center line of the cylinder is: ? = ? 4?? (? 2 − ? 2 ), where P is the difference in the pressure between the ends of the cylinder and ν...

An annular cylinder has an inside radius of r, and an outside radius of rz (see figure). Its moment of inertia is I = 2m(12? +122), where m is the mass. The two radi are increasing at a rate of 4 centimeters per second. Find the rate at which I is changing at the instant the radii are 6 centimeters and 10 centimeters.

The members of a marching band form a rectangle with initial length L0=40 feet and initial width W0=20 feet. As their song begins, they begin marching so that the length of the rectangle increases at a rate of 3 feet per second, and the width of the rectangle increases at a rate of 2 feet/second. (a) Write an equation for area A of the rectangle of the marching band in terms of length L and width W. (b) Use implicit...
