A logic brain teaser.

Two ropes hanging from ceiling puzzle.

Y me wood rope hanging floating shelves set of 2 rustic wood hanging shelf with 4 hooks wall hanging rope shelves for living room bedroom bathroom and kitchen 17 x 8 x 0 7 brown shelf 4 4 out of 5 stars 503. If the cable is 80 m then half of it is 40 m. You re in a room with a ceiling exactly 100 feet high. The cable has to be doubled back upon itself and the two poles must be coincident and 0 m apart.

Here s another oldie from a book slightly paraphrased to make it more quantitative. If you light one end of the rope it will take exactly one hour to burn all the way to the other end. A mass hanging from two ropes. He can t cut the one rope in half because the ropes are non homogeneous and he can t be sure how long it will burn.

This part is actually a trick question. Two fifty foot ropes are suspended from a forty foot ceiling about twenty feet apart. Two thin but sturdy ropes are hanging from fixed hooks at the ceiling and just touch the ground close enough that you can grab both of them at the same time comfortably. Bends are knots to tie two ropes together.

But it doesn t have to burn at a uniform rate. Armed with only a knife how much of the rope can you steal. The cable therefore is hanging directly downward. Each rope burns in 60 minutes.

He actually wants to measure 45 mins. Let s begin by drawing our mass hanging from the two ropes. The two poles are a distance of 0. This is the only equipment you can use.

Here is a selection of knots for joining ropes and also some knots where the rope is tied upon itself such as the heaving line knot and the sheep shank the water knot is an excellent knot for use with flat webbing material. In other words half the rope may burn in the. But notice 40 m from the top of a 50 m pole is already 10 m above the ground. An object is hanging from a ceiling and two ropes are holding it up at angles.

You are given two ropes and a lighter. Find the tensions in the two ropes. Find the the tension of the ropes. A mass of 108 g is hanging from two massless ropes attached to the ceiling.

The easiest way to solve this problem is by. One rope makes an angle of 50 with the ceiling while the other makes an angle of 29. He will burn one of the rope at both the ends and the second rope at one end.
