Why does paper stay folded?
A fold or bend in a paper becomes permanent because you are damaging the fundamental structure of the fibers that compose the paper, pushing them beyond their elastic limit into a state of permanent physical change.
Why does folded paper hold more weight?
Folded paper bears more weight than a flat sheet of paper because of it’s increased thickness. The more thickness of sheet the more load bearing capacity.
Why can’t you fold a piece of paper more than 7 times?
The commonly accepted wisdom is that you can’t fold a single sheet of paper in half more than seven times. The problem with folding paper in half multiple times is that the paper’s surface area decreases by half with each fold. With the assistance of a forklift and steamroller, they get the paper to fold 11 times.
Why does paper wrinkle when it gets wet?
By wetting the paper, cellulose fibers expand in inconsistent ways, creating warpage. When it dries, it does not get dried uniformly across the sheet (meaning, there will be parts that are about 10\% water by weight, parts that are 12\% by weight, etc.).
Does folding paper make it heavier?
As weight is product of mass and acceleration due to gravity. And gravity is inversely proportional to the square of distance from the center of earth. So the force on the folded layers would be less. So unfolded paper would be more heavy then folded one.
Why is rolled paper stronger?
Tightly rolled tubes are a strong shape because they distribute weight, which pushes on every part of the paper, not just one spot. If you make a rectangle or square out of newspaper tubes and press on it, the weight pushes down on just one side.
Is it true that if you fold a paper 42 times it will reach the moon?
Given a paper large enough—and enough energy—you can fold it as many times as you want . Problem: If you fold it 103 times (only if you could ) , the thickness of your paper will be larger than the observable Universe: 93 billion light-years. Yes,on folding the paper 42 times ,it would reach the moon.
