MythBusters - Phone Book Friction

It's not clamping on the spine.

Fun fact: once they reinforced the spines of the books and tried it again they literally had to use an APC and a light tank to pull them apart.

[@PraiseTheLordyourGodJesus]

Ephesians 6:10-18 says, Finally, my brethren, be strong in the Lord, and in the power of his might. Put on the whole armour of God, that ye may be able to stand against the wiles of the devil. For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand. Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness; and your feet shod with the preparation of the gospel of peace; above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked. And take the helmet of salvation, and the sword of the Spirit, which is the word of God: praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints. The bible is no old book. You have to really let Christ open your eyes; to see the world in shambles. Many people say it's a religion to lock up people in chains, and say it's a rule book.. why? Because people hate hearing the truth, it hurts their flesh, it's hurts their pride, it's exposes on what things have they done..people love this world so much, s*x, money, power, women, supercars.. things of this world. Still trying to find something that can fill that emptiness in your heart. You can't find that in this world.. only in Christ, the bible is no chains, it's a chainbreaker. Breaking your sins into pieces... Repent now, and turn back to the true Lord only.. God bless. 😊😊

@Owen Yin Well the tape is there to prevent the books from just opening. If they open then the pages are no longer touching and there is no friction, which wouldn't really be a test of this myth.

It is just a friction thing. The pages are pressed together, so a vacuum can't form as there is no space for an absence of air. When you have hundreds upon hundreds of pages not only pressing together but also pinched together, you have a great amount of force to overcome.

[@lanno666]

FYI, separating these two books will require 10^83 newtons of force. The gravity pull between the sun and the earth is 10^22 N.

[@Michael-qi9tw]

The books have a friction coefficient that’s greater than 1 meaning any force you put upon will be redirected in the opposite direction at least to the same magnitude you pulled. Velcro has a friction coefficient of 6 meaning that it’s impossible to pull Velcro’s apart when sliding the two surfaces against each other.

[@bmartin5525]

That's not quite how friction works. The friction coefficient tells you how much of the normal force or the force pushing the object against another surface (most of the time gravity) gets translated into a resistive force if you try to slide it. A block of wood with a coefficient of friction of 1 between it and the ground "pushes back" with a force equal to it's weight if you're just pushing it across the ground. Also, the coefficient of friction is always between 2 surfaces. There's no coefficient of friction for just Velcro, but there is for Velcro on Velcro.

[@ubersham]

They didn't try the air compressor. Blowing air between the pages reduces friction, allowing the pages to be pulled apart much easier.

[@barakoxman4951]

the lady's completely wrong at the end I think...friction is independent of surface area. The harder you pull on the phone books, the greater the pressure you're compressing the interlocked pages, thus increasing the friction.

what if you pull it out vertically instead of horizontally

[@haveiszalfaroqie1628]

SuperReachfreak Well, it's the only obvious way to open the book without ripping them apart

[@RaspK]

Yeah, but there's an inherent problem with that. By having the pages kept shut, this effectively applies a force perpendicular to the pages' plane; this actually *increases* friction (as would be the case with two objects with the same μ but different weights when placed on level ground).
