Friction is really good for only one thing…okay, two…no three. One important use is the simple act of striking a match. This would come in handy whilst camping, setting the stage for a special dinner for that special someone, arson, lighting a fuse of an M80 on July 4th or offering a light to that special someone you are hoping will come back to your place for that special dinner. (Full Disclosure: I would never date a smoker! Lips that touch tobacco shall not touch mine.) Besides, the above would have to take place in the rain or snow outside a Smoke Free bar. There are many ways to strike a match but I will leave those details for you, dear reader, to research. I will simply say: Watch any Bogart film. Striking a match is not to be taken lightly. The person striking the match must consider the coefficient of friction (fr). That is a number that is the ratio of the resistive force of friction (Fr) divided by the normal or perpendicular force (N) pushing the objects together. This is easily shown in the equation: fr=Fr/N. If you’re having trouble following all this, I would say: Trust Me or Get The Cliffs Notes.
But I digress.
Another vital use of Friction is the idea that involves static cling. As someone who has washed more than a few loads of soiled clothes, there is nothing worse than static cling. My personal solution to this problem is bounce. The only issue I have with dryer sheets is that the sheet clings to the clothes. This can be a very serious issue if you have to get dressed quickly. It is common when that special someone has a special someone who comes home from a business trip to Toledo. That rascal dryer sheet can cling to the back of your shirt or pants. People will stare. But static cling isn’t all bad. At parties it can be great fun to rub an inflated balloon on your shirt. The static will allow the balloon to stick to you. All kinds of obscene situations can be arranged.
A third and perhaps the most important use of friction is starting a fire. Putting matches (and Bic BBQ starters) aside for the moment let’s shed some light on fires. It is a well known fact that friction produces heat and enough heat can cause a flame to appear. We’ve all heard that one can rub two sticks together and make a fire. In fact, that is usually done in movies (Westerns). But if you ever saw two boy scouts rubbing two sticks together you would observe an exercise in frustration. It isn’t that simple. However, variations on that idea do exist. Take a close look at the photo below:

This method actually works. Notice the smoke wafting near the guys foot. This, dear readers, is friction in action! Personally, I would not attempt this in the heart of New York City. One problem is finding appropriate sticks. That would entail visiting Central Park. And most of the sticks readily at hand there would be covered with dog germs. In extreme cases of darkness, i.e., a Blackout, one could use a flashlight. However, when the AAA batteries lose power there is always the torch. (Not a British ‘torch’…that’s a flashlight), but a real kerosene-soaked torch like the angry villagers in Frankenstein (1931 Dir. James Whale). That would, of course, bring the Law down on you. You would likely end up making candles in Dannemora.
I will follow up this enlightening blog post with something else that has annoyed me for years…Gravity.
