Good evening all

Nothing is good enough for this thread even though this thread is good for nothing. Nothing deserves an answer except for the following question -

If I am building a triangle to support a seat, using timber that is 92 mm wide (when viewing the triangle in plan), so that the upright is 375 mm long and the right-angled top is 435 mm long, what's the untrimmed length of the hypotenuse, (to determine how long to cut the piece before trimming the ends to fit and take account of the angles at each end)?

Nothing could be simpler, but perhaps this is not simpler than nothing.

A strange conundrum I admit, but then again, this is Sunday evening.

Regards

G'day,

Nothing but to do and read this thread or go to bed. Think I'll go to bed and have a sleep and do nothing while I'm at it.

Give us a sketch pete if this is wrong cause this is how i've interperated you so far.
Normally the hypotenuse is the square root of the sum of the squares of the oyher two sides ( in a right angel triangle)
or 375 squared = 140,625
435 squared = 189225
Total = 329850 the square root of this is 574.33 mm

Assuming your maths is correct (not gonna check it) you're right in assuming pythagorus' theorem applies. However, your figures give us the total length of the diagonal and don't allow for the 92mm thickness of the top & side pieces. So, unless we know how he's joining, it can't be calculated.

For example, let's assume he's just going to butt-join to the inside of these two pieces. We could go the technogeek route and calculate both required angles (TanX = OppX/AdjX, and TanY = AdjX/OppX) to use the resultant angles in calculating the hypotenuse for each triangluated end. (HypX = OppX1/SinX & HypY = OppY1/SinY, where OppX1, OppY1 = 92mm) We could then subtract these two lengths from the total external hypotenuse that you've previously calculated to give us the outside length of the brace.

We could go the engineering route and work it out more simply. (TanX = 375/435) Having one angle, we know the other angle is 90°-X° but we don't need to work even that out 'cos all we're after is the hypotenuse and simple geometry tells us that both triangulated ends will be the same, so we work out the hypotenuse for one end (HypX=92/SinX), double it and subtract that result from your length.

Or, as woodies, we could joint the top/side together, use a straight edge to scribe the diagonal and measure it with a tape.

Simplest of all is the yuppy method. Ring up a woodie, give him the specs and say "do it."

Do you want to hear the programmer's route? "Not our problem, that's hardware."

How about the housewifes? :confused: No? Spoilsports!

Why is Pythagorus' theorem still called a theorem and not Pythagorus' law?

You're well on your way to becoming an expert then.

After all, an expert specialises more'n'more in a smaller'n'smaller field of study until he knows absolutely everything about nothing.

There are a few (actually hundreds!) of consultants from one of the big four (near, well actually at the top of, the alphabetic list) where I work that fit this category very well indeed...

The sad thing is that they will keep insiting that they are right, when all available evidence pouts to the contrary. Ah well

That reminds me of a conversation I overheard in the uni caf while doing my degree...

#1: The answer is definitely Yes.
#2: Wrong. Facts show it is No.
#1: Then the question was posed incorrectly.

I've no idea what subject they were talking about, not sure I want to know. But I'll bet they were working on a master's degree.

Nah...that degree of sophistry would have to lead to a PhD.

(Sorry Iain and all the other PhDs here )
