The area the question wants is between θ = π / 2 and θ = 3 π / 2 for the graph r = θ. Therefore, I computed the integral ∫ π / 2 3 π / 2 θ d θ = π 2. I even checked it with a ... WebMar 4, 2010 · I'm not sure what you mean by "the helical sweep only makes springs" - it makes whatever section you sketch, surely? If you're trying to model an auger (like a grain elevator, or archimedes water screw) then I'd probably start by revolving a solid "blank" and then using a helical sweep to cut away the slot (you'll need to …

Im a dumbass when it comes to openscad, but im using a few scripts now and then to do certain things, spirals for example. I have a script that i dowloaded years ago, that no longer works when i reinstalled my computer, and probably downloaded a newer version of openscad. WebThe Archimedean spiral was first studied by Conon and was later studied by Archimedes in On Spirals.Archimedes was able to find various tangents to the spiral. He defines the spiral as: If a straight line one extremity of which remains fixed is made to revolve at a uniform rate in a plane until it returns to the position from which it started, and if, at the same time as … chinese food east bay largo fl
