First electrical power output from a Pyramid

[MT]

@skywatcher, olivier

Thanks a lot, this is what looked for. Yesterday I made paper pyramide with 60degrees cut angles at top 30deg at bottom. But bottom was still not right now i see it should be ~ 35deg. I just want to compute it properly in line with saying 3x measure and 1x cut. Also i think I was ripped off by local hobby shop 6.80euros for meter of square tubes. Bastards. Later spoke to a guy in metal business ~2euros is usual price at least in mine country.

Great - could you measure the angles.

Here's the issue. I'm in the US I had to buy 3/8" tubing, 19.04mm, so I'm trying to redraw these.

Also I'm not working on the apex templates but the other end which is just a plain 45 degree angle.

Could you show the lengths also. I think you will find that they change with the angle.

The software gives the lengths only with 1 mm accuracy (obviously it's not intended for modeling small things ) but you can get the lengths by constructing the whole thing on paper (for this the angles are sufficient). When constructing it on paper or drawing lines on the steel before cutting it i think working with the angles is better than working with lengths.

The angles should be independent of the tube size, as long as the tube is quadratic.

I guess you are speaking about the shop whose name has 3 characters and begins with 'O'.
