An arch bridge is a bridge shaped as an upward convex curved arch to go through the vertical loads. The bridge is operated by moving its weight and other loads into a horizontal thrust that is restricted by the strong arches at either side.

An arch of a bridge is semielliptical, with major axis horizontal. The base of the arch is 30 feet across, and the highest part of the arch is 10 feet above the horizontal roadway, as shown in the figure. Find the height of the arch 5 feet from the center of the base. (Round your answer to three decimal places.)
A bridge with a supporting parabolic arch spans 60 ft with a 30
ft wide road passing underneath the bridge. How high must the arch
be in order to have a minimum clearance of 13 ft above the
road?

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).
Question 14(4 points) narch that suports a bridge over a river is parabolic and spans a horizontal distance of 40m. An equation of the parabola is y = -0.0082? + 1.122, where y meters is the height of a point on the arch above the river, and x meters is the horizontal distance of that point measured from one side of the arch. a) Write an inequality to represent the cross-sectional region between the arch and the river b) Sketch...
1) A bridge is built in the shape of a parabolic arch. The bridge arch has a span of 180 feet and a maximum height of 30 feet. Find the height of the arch at 20 feet from its center. 2) A searchlight is shaped like a paraboloid of revolution. If the light source is located 3 feet from the base along the axis of symmetry and the opening is 8 feet across, how deep should the searchlight be?
