What shape?

[RicB]

Imagine you have a plank of wood.

In that wood there is three holes - a square, a triangle and a circle.

The challenge is to design a solid shape that will pass completely through all three holes (one hole at a time) with a sliding fit.

Cone

What kind of triangle would it be?

[chrisb691]

It could be a cylinder.

[RicB]

Cone - sorry no.

Cylinder - sorry no.

What size triangle, not important. It will become apparent when you know the answer. :rolleyes:

[pugwash]

A cylinder takes care of the circle and the square, but how to incorporate the triangle? I'm gonna have to think about that.

[Manuka Jock]

And a cone takes care of the triangle and the circle :)

:wink: The task was to
"design a solid shape that will pass completely through all three holes (one hole at a time) with a sliding fit."
no mention of it having to be a watertight fit , so ........ :D

[stuffy]

How about a saw?

It would touch the triangle at 3 points, and, I believe, would give a sliding fit (provided all hole are sized suitably).

The same with the base of the cone re. the square hole , but apparently neither a cone nor a cylinder fit the answer.

Guys, has PM'd the correct answer with a link to the solution. I wasn't aware there was such a link but thank god for because I am a lousy artist.

The object in question has to be a sliding fit, ie slides through with no gaps, through all three.

If you want the answer, PM me and I will fwd you the link sent me.:D

The answer has to be posted on this thread by the person claiming to have it . The rest of us did so with ours .

The shape is a cylinder of height equal to the diameter of the base that has been truncated by two planes that intersect with the base at tangents on opposite points of the circular base, and intersect at the top of the cylinder along the line of the diameter.:) Circle, square and triangle...

If the above means nothing to you, the shape can be seen here - Triangle Circle Square (http://sweger.net/~andrew/Triangle-Circle-Square.html)

Google takes the fun and hard work out of Quizzes. :C (did I spell quizzes right?)

After reading the answer, I noticed that some of the important info (measurements) were left out of the original question.

So apart from
"oops, I've cut the wrong end of the new turning chisel I was making "
does that shape have a name ?

[Chief Tiff]

I think it's called a precision beading and parting tool, made from round stock, except the handle and all of the shank appears to have fallen off....:D
