The new river gorge bridge in west virginia is a 516 m long steel arcch. How much will its length change between temperature extremes -18.6 degrees Celcius and 35.6 degrees celcius. Please show work so I can learn how to do this.
Homework Answers
Coeeficient of thermal expansion for steel
alpha = 12*10^-6 /K
dT = 35.6- (-18.6) = 54.2
L0 = 516 m
L = L0(1 + alpha*dT)
L - L0 = L0*alpha*dT
dL = 516*12*10^-6*54.2
dL = 0.335 m

The New River Gorge bridge in West Virginia is a 3,030 ft long steel-arch bridge. A natural temperature range at the site is -5°F in winter and 100°F in summer. The bridge surface can heat up to 120°F a. Convert the two extreme temperatures to Celsius. G= 3 (F-32) (= $(-5-32) --28.72 b. Convert the bridge length to meters. c. Find the bridge total length change from winter to summer (in meters).

A long steel I-beam used in bridge construction has a length of 16.0 m. The beam may be exposed to temperatures as low as −16°C in the winter and as high as 32°C in the summer. What is the difference in length of the beam between these two temperature extremes? (Give the absolute value of the difference. Enter your answer in mm.) mm

A bridge with a steel framework is 500.000 m long on a winter day when the temperature of the steel is 5.0 'C. The coefficient of linear thermal expansion of steel is 11.0x107C. The bridge is built in with the two ends anchored in rock and it has a hinge at its center in case it expands past its original 500.000 m length. y = ? 250.000 m (a) How long is one half of the bridge at a temperature...

1. The George Washington Bridge crosses the Hudson River between New York and New Jersey. The span of the steel bridge is about 1.70 km. What might be the difference between the maximum span and minimum span over the course of a year, if the temperature can vary from a low of −15.0°F in winter to a high of 106°F in summer? Expansion coefficient of steel is α = 12.0 × 10^−6 K^−1. 2. A 2.30 m length of copper...

Steel train rails are laid in 14.0-m-long segments placed end to end. The rails are laid on a winter day when their temperature is -5.0 ∘C. How much space must be left between adjacent rails if they are just to touch on a summer day when their temperature is 33.0 ∘C? If the rails are originally laid in contact, what is the stress in them on a summer day when their temperature is 33.0 ∘C? Please answer both questions

1. The continental shelf off Virginia and North Carolina is roughly 70 km wide and 310 km long. During the summer, the average daily irradiance over this region is 250 Watts per square meter. Assume that the surface mixed layer is 10 meters deep on average and that 25 percent of the heat is absorbed and retained in this layer. After 30 days, how much warmer (temperature increase) will the surface mixed layer be? (30 points) Remember: Q = c...
