please show work and detailed steps!
[2 point] The New River Gorge Bridge in West Virginia is a steel arch bridge 518 min length. How much does the total length of the roadway decking change between temperature extremes of -20.0°C and 35.0°C? The result indicates the size of the expansion joints that must be built into the structure.
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.
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
Could you please show how you did your work? Thank you!
5. The cables of a suspension bridge are in the shape of a parabola. The towers supporting the cable are 600 feet apart and 80 feet high. If the cables touch the road surface midway between the towers, what is the height of the cable at a point 150 feet from the center of the bridge? (5 points)
