- Where h, k, are the
**pitches**of the two given screws. - P p are the
**pitches**of the two screws. - It is to be noticed that the parameter c of the cylindroid is unaltered if the two
**pitches**h, k be increased by equal amounts; the only change is that all the**pitches**are increased by the same amount. - Hence we can adjust these so that the surface shall contain the axes of the two given screws as generators, and that the difference of the corresponding
**pitches**shall have the proper value. - In particular cases the cylindroid may degenerate into a plane, the
**pitches**being then all equal.
