Can the freight truck go through the tunnel?
An analytic expression for parabola;A freight truck is tall and wide. Can it pass through the tunnel?If the tunnel is equipped with a double lane, for safety reasons, is there a separation belt in the middle of the tunnel, then can the freight truck pass through the tunnel?Parabolic problem, generally establish a rectangular coordinate system, the length of the transformation into the coordinates of the point, to seek analytic formula, the use of analytic formula to solve practical problemsAccording to the problem,,,.The analytic formula for the parabola is to take or substitute it
Figure, the tunnel section is composed of rectangular and parabolic rectangular, length, width, with the straight axis, the axis perpendicular bisector of a line segment, a plane right angle coordinate axis is the symmetry axis of the parabola, the vertex to the origin of coordinates for the distance.
