ENG 303 4b. The original Tacoma Narrows Bridge was the first suspension bridge built across the Puget Sound in Washington. The bridge was strong but relatively light, narrow, and as it turns out—(too) flexible. On the morning of November 7, 1940, in a 42 mph (68 kph) wind, the 2,800-foot (853-m) main bridge span went into a series of torsional oscillations (side-to-side and up-and-down motion) in which the amplitude (size of the motion) steadily increased. This movement tore several suspension...

You decide to get on one of the swing rides at the amusement park. The seat is a 20 kg, 12-m long uniform board suspended by 2 cables. You have a mass of 65 kg and sit 3 m from the right cable. Each cable has a length of 40 m, a radius of 0.5 cm, and a Young’s modulus of 200x109 N/m2 . Assuming that you and the swing are in equilibrium, what is the tension in the left...

A steel rod 30.0 m long, installed when the temperature was 10°C, is in a bridge that heats up to 40oC on a hot summer day. Steel's coefficient of linear expansion is 1.2 × 10-5 K-1. The bridge is built so the rod has an expansion space of 5 cm. Is this enough space? What is the increase in the length of the rod, in mm?

A steel wire in a piano has a length of 0.5000 m and a mass of 4.200 10-3 kg. To what tension must this wire be stretched so that the fundamental vibration corresponds to middle C (fC = 261.6 Hz on the chromatic musical scale)? -------- Two pieces of steel wire with identical cross sections have lengths of L and 2L. The wires are each fixed at both ends and stretched so that the tension in the longer wire is...

You sign up for a bungee jump off a tall bridge. A thick rope with a fixed length of 16.0 m is tied to the bridge, and a bungee cord with an unstretched length of 8.00 m is then connected to the rope. The other end of the bungee cord is attached to your legs. You step off the bridge, falling from rest. The bungee cord does not start exerting any force on you until you have fallen a distance...

A person drops a cylindrical steel bar ( Y = 8.0 × 10 10 Pa ) from a height of 1.10 m (distance between the floor and the bottom of the vertically oriented bar). The bar, of length L = 0.67 m, radius R = 0.75 cm, and mass m = 1.80 kg, hits the floor and bounces up, maintaining its vertical orientation. Assuming the collision with the floor is elastic, and that no rotation occurs, what is the maximum...
