Homework Help Overview

The discussion revolves around measuring the parabolas formed by the suspension cables of a bridge. The subject area includes geometry and physics, particularly focusing on the properties of parabolic shapes in structural contexts.

Discussion Character

  • Exploratory, Conceptual clarification

Approaches and Questions Raised

  • The original poster attempts to explore methods for measuring the parabolas, suggesting the use of a point of reference. Some participants provide insights about the geometric properties of the parabola related to the bridge's structure, such as the vertex location and symmetry.

I was given the assignment to measure the parabolas of a suspension bridge. I have some ideas for how to go about it, like using a point of reference and going out from there. I was wondering if anyone had any other ideas. Thanks!

Some important aspects about a bridge to note are that:
  1. The vertex of the parabola is at the centre of the bridge, from a side view. This is obvious since it hangs freely and the lowest point would be in the middle.
  2. The heights on each end of the bridge are equal so if the vertex is at (0,0) then one end of the bridge will be at (x,h) and the other end will be at (-x,h).

This is all the information you would need to find the parabola that defines the suspension cable.
 
That is great! thanks for the help.
 
Glad to help :smile:
