Ever hear of Hooke's Law?

[navycop]

Was helping my son with homework. It states that the displacement of an elastic material (spring or rubberband) is directly proportional to the force applied. It is crazy how all these guys get "laws" named after them. I mean take Charles's Law about temperature and volume, then Boyle's Law about pressure and volume, Gay-Lussac Law pressure and temperature, Ohms Law about electricity.

 

[mredburn]

You forgot Murphys law

 

[bensoelberg]

Or Murphy's Law about stuff going wrong...

 

[navycop]

You forgot Murphys law

I should of remembered him. He is always around when I am in my shop.

 

[bensoelberg]

See what a jerk Murphy was? I come up with a clever comment, but because of that stupid law, Mike beats me to the punchline.

I would rather have Names used than a law named with only a number!

It is easy to get a law named after you.

Just discover and codify a new physical principle. Or do something so bizarre that they have to make a new law to forbid it.

 

[SteveG]

O'Brien's Law: "Murphy was an optimist."

 

[The Penguin]

don't forget about Coughlin's Laws

 

[Smitty37]

Hmmmm

Or Murphy's Law about stuff going wrong...

With it's many codisils - basic law is "Anything that can go wrong will." First codicil adds "at the worst possible moment". There are lots of others.

If you're bored, here is a full list of eponymous laws. List of eponymous laws - Wikipedia, the free encyclopedia

FYI an eponym is a person (real or fictitious) from whom something is said to take its name. The word is back-formed from "eponymous", from the Greek "eponymos" meaning "giving name".

Chuck Norris' law is the only law!

I always liked DAD'S LAW.

Nice list!!

My least favorite is the Dilbert principal. Mainly cause it causes me so much grief on a daily basis. My favorite is Occams Razor.

 

[LeeR]

I subscribe to Krug's Law (I named it after a engineer/machinist friend of mine), and put it to practice often:

"Why buy something off the shelf when you can make it for twice the price?" ...

 

[raar25]

To answer your first question, yes I have have heard of hookes law. The thing to keep in mind is it only applies to small changes in the spring/elastic which do not exceed the elastic limit and the potential energy increase as the change in spring/elastic potential energy increase as the change in length increases.

Hooke must have been a pretty smart guy huh! Good luck with the homework, I couldn't calculate the stress/strain curves today if my life depended on it.

What???

Basically, it works until you deform the material. At that point you have a new stress/strain curve for the new shape/properties.

 

[cnirenberg]

I'm not much a conformist, but I do subscribe to Zappa's Law. It states "Watch out where the Huskies go, an' don't you eat that yellow snow..." Sorry to bring down the conversation to a much lower level.

 

[carverken]

Then there was O'Dools law. It is very similar to Murphy's
What will go wrong, already has, you just dont know it yet.

And just what would that "snow" stuff be????? assuming that it is 'stuff' and not some figment of someone's imagination.:biggrin:

Don't stretch it too far

What???

If you stretch it too far it won't return to it's original size. That will cause it to break or become less elastic.

For you "tutors" out there, you might take a look at Khan Academy.

I found this site a couple of years ago when helping with calculus homework.

Some of the videos are great, some not so but a good place to get some help with the tutoring, and a wide selection of subjects.

Mine's off at college now so I'm off the hook...... mostly.

Help....???

I was lucky, I rarely had to help my kids with their homework. Of course they sometimes got upset with me when I would disagree with their teacher about something.

I used to tell them "I'm right, but if you care about your grade put down what the teacher said."

The only time I ever pushed it was once when the Earth Science teacher didn't know which way the wind was blowing. That one I did go in and meet the teacher and carefully explained that North wind referred to the direction the wind was coming from not the direction it was going.

 

[jd99]

I used to have a Murphy's Law Poster in my other shop, I remember one thing from it..... "A Smith and Wesson beats Four Aces" :biggrin:

[JohnGreco]

What's the one that says the mail will always be late when you're waiting on a package? Whatever it is, I have that living out right now. Maybe Greco's Law, because it seems to happen without fail for me!

I have another version of that one....the mail will always be late...unless you have 15 packages to get out ... then the pick up will show up 20 minutes before you are finished packing everything.

Then there's the law of Supply and Demand (who were those 2 guys, anyhow?).

Hmmmm

My favorite has always been Zymurgy's Law of Evolving Systems Dynamics which states "Once you open a can of worms, the only way to recan them is to use a larger can".

my stepson is taking algebra. My wife and I are both engineers. She's electronics (though not active), and I'm a civil PE. I was also a teaching assistant for calculus and a math tutor in college. Around here - we know how to do math...well the stepson doesn't - but he's getting better.

I think the algebra teacher doesn't know how to teach. :biggrin:

 

[Ted iin Michigan]

Penguin - I'm a Civil PE. also. But my wife is a Human Resources professional. Interesting pairing but it works (for us). When homework time came around (like every night for MANY years) I got the call for Math/Science and "anything" technical. Still get the occasional request for assistance from niece who lives across the road. One of my favorite quotes was when youngest daughter went off to college. She told us she was going to "major in Psycology - and minor in Engineering". Lord, I love my kids.

[Smitty37]

Hmmmm

I worked as a Electronics/computer technician ( Navy Training) and Test Engineer (also manager) who finally got my BS degree in Political Science. I could offer help during elementary and secondary years in any of my kids subjects except foreign language but particularily math and science. My wife (who worked as a stay-at-home and keep the kids safe and on the straight and narrow Mom until the youngest were juniors in high school) went to one year beyond high school to get a secretarial certificate and was good at spelling and English - we raised:

1 EE major who works in a bank.
1 Accounting major w/masters in accounting - who is a partner in large accounting firm
1 Education majors w/masters in education - who is a high school principal
1 Political Science major w/masters in education - who is a high school principal
1 Sports Education major w/masters in Athletic Administration - who is a sports complex administrator for a town in NC
1 college drop out who before he began his now 10 year battle with cancer was the Chief Operating Officer for a 30 motel chain. He now operates his own business as owner/manager of a number of rental properties.

In short, the kids are all over the map with careers, with none who ended up like me or Mom in their career choice.
