Dr. Ben Blalock has hired us to determine the length of the power lines between two towers, and the tension in the power line. We do this by sending a longitudinal pulse and then a transverse pulse down the line. It takes 0.17 sec for the longitudinal pulse to return, and 7.6 sec for the transverse pulse to return. The power lines are made of 1.0 inch diameter aluminum wire, with E=10.3x106 psi and weighing 172 lb/ft3.
a.) What is the length of the power line?
ANSWER: 1416 ft
b.) What is the tension in the power line?

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
