Determine the response of the system of Chapter Problem 6.14 if the crane is disturbed resulting in an initial velocity of 10 m/s downward.
Problem 6.14
An overhead crane is modeled as a two degree-of-freedom system as shown in Figure P6.14. The crane is modeled as a mass of 1000 kg on a steel (E = 200 X 109 N/m2) fixed-fixed beam with a moment of inertia of 4.2 X 103 m4 and length of 12 m. The crane has an elastic steel rope of diameter 20 cm. At a specific instant, the length of the rope is 10 m and is carrying a 300 kg load. What are the two natural frequencies of the system?
