Modelling an underpass |
2010-05-11 |
|
Sue pose la question :
An engineer at the Ministry of Transport is creating the plans for a new road. This road
will cross the path of a busy railway track so it will be necessary to built an underpass for this road.
This underpass will be in the shape of a parabolic arch.
The specifications include:
-the road must be at least 10 m wide and it must have shoulders at least 2 m wide on either
side of the road.
-there must be a clearance of 3 m over all areas of the road.
What quadratic equation could you use to model this bridge.
