Earning triangular rollers. Action 2 – rounding in excess of 3 of the edges of a hexagonal prism.
A curve of constant width is a two-dimensional condition whose width, as measured with calipers, is the identical, irrespective of the orientation of the curve relative to the calipers. You can extrude these types of a curve into a three-dimensional roller that will have a regular peak as you roll it all around on a flat floor. A board supported by a pair of such rollers will transfer horizontally devoid of any up and down movement. A circle is a curve of continuous width, but it really is not the only just one there are many others. A Reuleaux triangle (an equilateral triangle where by every single side is a circular arc centered on the opposite corner) also has continuous width, and you can use it as the basis for rollers that glimpse like they shouldn’t function at all. Influenced by my daughter’s superior faculty job I built an case in point out of wood.
