Since the two towers are 150 m apart, they are at x= 75 and x= -75. The cable attaches to the towers 22 m above the roadway (y= 0) so the cable passes through the points (75, 22) and (-75, 22). Since the parabola is symmetric, we must have y= ax^2+ b. Also, the minimum is at (0, 7). Put x= 74, y= 22, and x= 0, y= 7 into equation to solve for a ...
A hiker who weights 985 N is strolling thru the woods and crosses a small horizontal bridge. The bridge is uniform, weights 3610N and rests on two concrete supports, one at each end. He stops 1/5th of the way along the bridge. What is the magnitude of the force that a concrete support exerts on the bridge First at the near end and at the for end???
Oct 14, 2008. #1. The cables of a suspension bridge are in the shape of a parabola. The towers supporting the cable are 400 feet apart and 100 feet high. If the cables are at a height of 10 feet midway between the towers, what is the height of the cable at a point 50 feet from the center of the bridge? S.
At the center of the bridge, the parabola will be 5 feet above the walkway. The cable material can be purchased from Company A for $52.75 per 10 feet with a shipping charge of $300.00 for the entire order or from Company B for $432.90 per 100 feet with a shipping charge of $350.00 for the entire order. You must purchase full 10-foot cables from ...
A child drops a ball from a bridge. The ball strikes the water under the bridge 2.0 seconds later. What is the velocity of the ball when it strikes the water? ^ Is the question. I have no idea how to calculate that, because there isonly one variable. Please help, this is due tomorrow.
The train is at point A; the start or near end of the bridge is at point B; the man is at point C; and the end or far end of the bridge is at point D. We don't know the lengths of AB (distance of train from the near end of the bridge) and BD (the bridge), so let AB = X miles and BD = L miles long.

A section of highway connecting two hillsides with grades of 6% and 4% is to be built between two points that are separated by a horizontal distance of 2000 feet. At the point where two hillsides come together there is a 50-foot difference in elevation. Design a section of highway connecting...
woodturner550. Feb 7, 2024. Applied Math. 10. Feb 8, 2024. In seven bridges problem, is it possible for a citizen of Konigsberg to make a tour of the city and cross each bridge exactly twice?
Jun 13, 2009. #1. A bridge over a river has a shape of a circular arc. The span of the bridge is 24 meters. (The span is the length of the chord of the arc.) The midpoint of the arc is 4 meters higher than the endpoints. What is the radius of the circle that contains this arc?
