Developed unfolded shape of a spherical triangle
Developed unfolded shape of a spherical triangle
(OP)
Dear All,
i am having a problem of drawing the unfolded elevation of a spherical triangle.
I want to cut a shape glass which later on i will gravity bend it to form a spherical triangle having a radius of 1123mm. The spherical triangle will form almost quarter of a hemi-sphere. Height of the spherical triangle measured from the top to the base is 1082mm.
Please help.
Thanks a lot.

But your question was done by the early topographer or catographers when they try to represent the map of the continents, the made a lot of trick to do it.

I've made this before in real life but you need to deform the metal sheet. We pressed a 16 gauge flat sheet supported on the end of a tube around a metal sphere under a press on that occasion, then cut out the section we wanted.

A similar problem arises in forming steel- as in water tower sections. There, the solution is partly trial and error.
In other words, there's not a simple solution.
