hello to all of you,
I have a question for the weekend, suitable for everyone, on the development of a sheet.
a 1200 mm high tower has a pentagonal base of side 400 mm.
the roof is equal to the base, the center is on the same vertical axis, but the vertices (and sides) are rotated of 36°.
you must draw and quote to the cent, the figure in plan of development. in one piece with 9 folds.
draw the fold lines and quotate the corners.
quote the rectangle containing development.
consider the altitude 400 mm. as the development of the neutral fiber of the sheet.
the peculiarity of this tower is that, while being straight, if I see it front as drawing, she hangs to right, if I look at it moving only 36°, she hangs to left.
you can not talk about optical effect, as it is all real.
ps. It would be good not to use programs.
the inner corner to be set on the bending machine is 180 - 360°/5 (lated) = 108° ?
or is 180° - 360°/9 (foot) = 140° ?
or is it...
