Logic puzzle #2

No Lifer
I need to enter a castle that is surrounded by a 5 meter wide moat filled w/water. I have an aversion for getting wet and only have two 4.5 meter long planks with no rope, nails, etc. How do i get across?

Just swim across and deal with the wetness; It's not gonna kill you.
 
put one board over a corner of the moat, the other piece on the center of the board, with the other end on the castle land
 
Well, considering a good castle wont have land on the inner side of the moat, just the castle wall - eldorado's suggestion wouldnt work. Since depth of the moat wasnt said - I'd suggest breaking the board into smaller pieces, finding the "lowest" edge of the moat, and digging a small canal to drain the moat 😀

edit: using the boards as shovels
 
at a corner, lay a piece of wood perpendicular to the line that makes the corner

|\ kind of like that, where the bottom and side line is the border of the water and the diagonal line is the plank

then connect a plank perpendicular to the first plank to the other corner

HOORAY, you nef

wouldnt a good castle have a DRAWBRIDGE?
 
Assume the boards are 4.5 feet long and 20 feet wide 🙂

Or assume the moat is really really shallow. You can then just lay the boards down in the water and walk across the top.
 
oh wait.... not enough wood to build a sufficiently large boat.

Here's another solution then:
Build 2 wooden buckets.. drain the moat.

If the board is wider than 2.2 meters, you can just lay one down diagonally and pray to Jesus you can balance across

If the depression is shallower than 3.7 meters and the water is shallower than J' (Half the distance the OP can jump x tan[56.3]), you can lay the planks touching the bottom of the moat in a V.

How will you attach the feet?

My solution would be to jam one plank into the side of the moat closer to the castle at an angle (say 35 degrees above the horizontal). Jam the other plank onto the side that you're on so that the farther plank's end lies atop the end of the plank you just jammed in. Now climb/walk straddle across.

Of course, if the planks are 6" wide, this wouldn't really work too well.
