I have a Question ; Why do the conquerers need to get to the other side of the moat . They have already won the battle. Why not fill the moat in with the dead bodies of the defeated enemy then walk across .

Castle - Back to the Logic Puzzles
A square medieval castle on a square island was under siege. All around the island, there was a 10 metre wide water moat. But the conquerors could make foot-bridges only 9.5 metres long. Nevertheless a wise man was able to figure out how to get over the water. What do you think was his advice?
(There's a place on the other side to put the bridge against, not just a sheer wall. the water moat has square corners - that section of the moat is about 14.1 metres wide.)


Spoiler for Solution


I hate to belinger a dead issue but I don't think your solution works. I don't understand the math behind your equations but I plugged the dimensions into a scale drawing program and the only way your diagonal solution can work is if the boards are completely unsupported at the ends. The dimensions can meet (perhaps a better word would be span) the required distances but they are not supported and will fall in the moat. Hopefully I'm not missing something obvious.

Yeah... I guess I made up a word (belinger). Sorry about that. Not sure where it came from.

you just have to put a foot bridge across the bridge and then just put one in the middle of it and it would work

Doesn't the bridge float. Use it like a boat.

I would just put 1 bridge across the corner and the other from the middle of that bridge the edge of the island. Like so:



that was my idea too ....

well, you could have the 9.5 foot long board and have a person have his legs tied to the board (maybe a captive) and then the army could walk across the person and the board, i am probably wrong
