For those who have not visualised the solution I offer the attached diagram which shows the single cut as the solid red line.View attachment 158047

As a construction worker....seriously not a single cut. No matter the tool used. Not even a jesus jizz powered laser could make that and be called a "single cut". You can't remark a compass and say north is east just because you wish it so.

Hello,

I actually had that same impression but did not comment on it.
Anyone who uses a power saw would view that as several cuts because you have to stop the saw and turn it and then start again to get that kind of cut. Even with a jig saw you cant make a single cut that does not have something else to it because you can not turn the blade 90 degrees as you are cutting without having holes drilled first and then you would have rounded corners which would not really work out right. So it's a bit tricky.
So i would have liked to see something like "single cut or contiguous set of cuts" or something to that effect in the description.
Did someone say zig zag cuts are allowed though? That may cover it.

It is still an interesting question though i think.
I also wonder if anyone tried to find another solution yet. It is possible that there could be a lot of solutions if we dont define the method of making the cuts more precisely.

If it were in imperial instead of metric that would help me. I didn't feel like converting it. Though I suppose I could just cut a board to his specifications and try it myself. And you're right, not even a jig saw could do it without pilot holes. I still think it's likely some kind of diagonal cut. Also couldn't you technically use a thick or Dado blade to knock off that extra .1m? Use the remaining .3m strip to glue or nail on the .9m side? Seems like cheating but if a diagonal cut is legal......

My bad I meant "staircase" cut being legal

 

To speak in such a manner truly implies you would know the answer to the riddle with having to impose your oratorical skills upon us. Seriously dude. Speak dumb. We like that.

Seriously dude, speak for yourself.

Great example!

 

The solution was described in posts 4, 10 and 15 a week ago. It is obviously (to most) an abstract, not a practical problem since it can only be solved with a dimensionless kerf.

All this discussion ad nauseum about tool types and cut shapes is therefore pointless as are complaints regarding word usage of members in the presence of multiple online dictionaries. Carry on, if you must.

So let me get this right now...

Some people have complained a little about how the wording of the problem may have not been adequate and now YOU are complaining about the complaining? Well now i am complaining about you complaining about the original complaining

Seriously though several people noticed that in problems like this it's hard to figure out exactly what the asker is asking sometimes because the wording is not explicit enough. This happens to be especially true of people who have worked in construction before and have used saws for many different jobs. A good example is when cutting rafters where you have to make several cuts which might be described as zig zag or 'notched'.

The converse is also true however. That by asking the question in a somewhat ambiguous way gets people to think independently from what you really intend and so may result in more solutions than you ever thought possible. It then also becomes a subject of some interesting discussion sometimes.

So dont get too upset

 

You misunderstand the source of my discontent.

Another point unrelated to the above: a hammer is not the right tool to solve an abstract math puzzle.

Hi again,

Oh ok sorry for the mixup.
Yeah hammers work on a lot of stuff (ha ha) just not everything.
Dont be too disheartened though these discussions can get pretty interesting in and of themselves, especially when you are 'bored' as the title suggested. Relieves a little of that boredom sometimes
