What can be the cross section at the cone?
Depending on the angle of inclination of the section plane to the base of the cone, four sections can be formed: a circle, an ellipse, a parabola, a hyperbola.
An example of architecture: the base of the Ostankino television tower in Moscow has the shape of a truncated cone:
You can build a truncated cone model with the following characteristics: height 185 mm, base diameter 90 mm, section plane inclination angle 55 °, section shape - ellipse. Download net truncated cone with an ellipse section.
The elliptical cone assembly scheme:
1. Connect the unfolding, so that you get a tube.
bases, we recommend that you first glue the auxiliary
items. This will allow them to hold them smoothly.
when gluing and will create the correct shape of the geometric structure.
3. We perform a similar procedure for the lower base.
4. Glue the base.
We suggest you build a truncated cone model with the following characteristics: height 110 mm, base diameter 100 mm, section plane inclination angle 65 °, slice thickness relative to the base 10 mm, section shape - parabola.
