If you were to measure the sway of the bridge in an 80 km/hr wind, you would find the following results: At t = Os, the sway = +45 cm (45 cm right) At t = 14s, the sway = -45 cm (45 cm left) a) What is the period of the swaying bridge? The amplitude? b) What is the equation of the sinusoidal axis? c) Construct a table of values and graph demonstrating one full cycle of motion. d) Suppose dampers were added to reduce the sway (but not period) by 50%. Construct a new table of values and graph to demonstrate one full cycle.6You attach an object to the bottom end of a hanging vertical spring. It hangs at rest after extending the spring 18.3 cm. You then set the object vibrating. Determine the period.

A pair of hoop earrings is in the form of peace signs and each earring can be made to oscillate withsimple harmonic motion about the point where the earring is attached to the hook that goes throughthe ear lope. The earrings are made of cylindrical silver wire having a density of 10.2 g/cm3and adiameter of 0.15 cm. Each earring can be thought of as consisting of a ring that is 1.5 cm in diameter, acentral vertical rod that is 1.2 cm in length and two diagonal rods, each 0.6 cm in length as shown in thediagram above. The distance from the pivot point of the earring to the center of mass of each diagonalrod is 0.975 cm. Based on this information, determine the period of this physical pendulum.
