Yes, you described it nearly perfectly. I'd make two corrections:

  1. In reality, the torque required to loosen a fastener doesn't always equal the torque applied when it was tightened especially if a lot of time has passed. But if you immediately loosen a fastener after tightening, it should be about the same.

>In order to have a screw torqued to 7 in-lbs, do I apply a load of 1 pound 7 inches away until it no longer rotates?

  1. I think this definition works, but when applied in reality it's more like: Rotate the screw until 7 in-lbs of torque is reached. Because as you know, more and more torque is required to spin a fastener the tighter it gets. When it's loose, you can only apply torque up until it spins.

So if a screw spins with 5 in-lbs of torque, then you simply can't apply 7 in-lbs - it moves before 7 is reached.

Fun fact. The speed of sound through a substance is dictated by the average speed of the molecules within that substance. Speed of sound in air is about 750mph, so the average speed of each air molecule at any given moment is 750mph.

But they only go extremely short distances before bouncing of another molecule and going another direction.

Edit: The average speed of air molecules is actually closer to 1000mph at room temperature.

Why's that?

It's evident the general public has no idea how to properly use credit cards. Everyone has been brain washed into thinking they're bad.

Yes, credit cards can ruin your life because they're interest rates are so high you can get out of it.

But what if I told you you can have credit cards, make free money by taking advantage of their cash back rewards, and pay $0 in interest in fees? Does that sound crazy?

Well it's not! Just pay the balance in full everyone month and it'll never accrue interest. Don't use your credit cards to buy things you can't afford (basically treat it like and a debit card - if the cash isn't in your account, don't buy it).

So if you have a credit card that offers 2% cashback and you use it to buy everything you would normally buy (groceries, gas, everything) and you pay it off every month - you will essentially be paying 2% less on everything.

Why would you not take advantage of that?

  1. If your debit card/credit gets stolen, you can shut it off. Cash gets stolen, you're shit out of luck.
  2. You're paying with cash everywhere, but only have $20 bucks at any given time?
  3. I didn't say my time is more valuable than yours. Our time is equal, which is why it would be awesome if you got up to speed in today's world and stopped slowing everyone down.
  4. You don't understand how credit cards work. I earn $100s in cash back every year and pay absolutely $0 in interest and $0 in fees. If you pay your cards off on time every month, there is no interest and the cash back rewards are quite literally free money.
  5. Using credit cards in the quickest and easiest way to build credit. Your a silly person if your prefer to do things the hard way.
  6. Yeah I kind of stretched on this one. No one disputes in person transactions.
  7. You'll know how much you spent in total, but won't know what you spend it on.

No but seriously, point number 4 is the biggest reason. It's free money. And no the interest doesn't outway it because there is no interest if you pay on time. And it much bigger than $0.02.

If you regular pay for things in cash, you are:

  1. Risking getting that cash stolen
  2. Risking losing that cash
  3. Wasting everybody's time as transactions take longer
  4. Losing out on cash back and other rewards that credit cards offer
  5. Hindering your credit score
  6. Forfeiting your ability to dispute any transactions
  7. Lessening your ability to track expenses.
