Before buying a car people should have to study kinetic and static friction. When there is no relative motion between two objects there is static friction. Static friction rises to meet force until it hits its max value (weight*grav*μs) then it drops incredibly fast and flat-lines at its kinetic friction (weight*grav*μk).

Rubber on concrete has roughly a 1.0μs and a 0.8μk whereas rubber on ice is closer to 0.15μk (can't find decent rubber-ice μs values.) The drop off for a slipping tire on ice is massive compared to concrete.


Years and years ago, I worked part time at a auto parts store. I had a guy come in and he wanted an emergency tow strap for his little poo poo box. Honda or something. Note he wanted it to do an illegal tow (IE: Just moving it) from his buddies place to his or something.. not to actually recover the car stuck in a snow drift or anything.

Anyhow, the thing was rated for 4000lbs breaking strength or something like

MAN! It'll break for sure! This is a piece of poo poo! You shouldn't tow a motorcycle with it!

Well, I'm not going to say it isn't a piece of poo poo (I like rope/chain combo personally) but I'm sure it'll work for you. What are you moving with it?

My Accord (or whatever)

Is it stuck?

No! But this isn't enough safety factor

Um, you do realize you're not lifting the car. You're just pulling it



I mean, you understand you don't need 3000lbs of force to move your car. You can push it yourself right?

Yeah

There you go.

Potentially stupid question, but why don't engines have some sort of thermal protection that shuts them down before they get hot enough to catch on fire or sustain damage? I mean clearly there's a temp sensor since an overheat light comes on, why doesn't it just shut off?

Some engines do. I know that the mid '90s Australian Fords with the I6 have some built in. Over a certain temperature the ECU starts shutting off injectors so some cylinders are just sucking cool air to help lower temperature. The service manual I have says that this will cause teh car to run rough. Imagine that.
According to the same manual the V8 method of protection is essentially spin the poo poo out of the fans and hope for the best. I can assure you this does not work.
There is nothing like seeing the temp gauge suddenly spike, the top marker on the gauge illuminating and hearing the car emitting a mournful "ding....ding....ding" to say "Hey! I'm hosed!". Wonderful thing to hear in the middle of the night on a forest road with no phone reception and only a few bottles of iced tea for liquid

The coolant tank smelt like tea for months.

I had a friend who told me once about my car then (made 100lb/ft torque on a good day), said if I took my wheel off and put a foot long bar in place, I could sit on it and the car would not be able to move me as I weigh more than 100 pounds. I told him to try it.

With a .78:1 fifth and a 2.90* final drive, it'd work for an awful lot of people.

My guess is it wasn't the engine itself that overheated, it was something close to the engine that overheated due to lack of airflow and revving the piss out of it for an hour.

Several years ago, a guy across the street from my high school had a heart attack while warming up his car. His foot ended up holding down the gas pedal and the engine revved until something caught on fire. Someone finally noticed all the smoke and flames and went over to investigate after about 30-45 minutes of constant revving.

Overloaded bed tipped over, probably bent the frame. The "crash" scene was somewhere else, this was just wear it was parked. Since the back is heavier than the front, when it was parked the bed took precedence and made the cab look bent over.

That appears to be an articulated dump, the load stuck in the bed when he tried to dump it and it lifted the cab up instead. Nothing is broken, the pivot in the frame is just allowing the cab to rotate to that side (it might be heavier on that side.)

E: Here you can see the bed on its side with the cab sitting normally

Well, I had a bit of a "Snowpocalypse" experience earlier today... it was snowing all day, an annoying sort of fine snow that seems to turns into pure slipperiness (ABS and TC were kicking in all afternoon). I'm coming back home from the market, and coming right to a steep downhill bit of road about a mile from my place.

Right away I think "this could be tricky", and I was right. The Accord in front of me locks up his brakes and slowly slides right into a car parked on the side of the road. Of course I touch the brakes, start to skid, then everything turns a bit slow-mo. I release the brake, spot a gap between the Accord and the car in the right-hand lane, add a bit of throttle and I make it through without any contact. That BMW winter driving course I took a couple of years back paid off.

And that's exactly what separates snow drivers from normal people. We know that "Add throttle, dab of oppo perhaps." is a valid and proper choice. 99% of the population is like ZOMG BRAKES I NEED TO STOP NOW STOP STOP STOP! Followed by the sound of folding metal and plastic.

Yeah, exactly. If I get trapped somewheres during a storm in my 2wd Ram, it's always funny passing stuck bro trucks as I go slow as gently caress with plenty of counter steer to compensate for the locked rear. They kind of look at me like I'm some kind of wizard, but it's just normal common sense driving. No matter how good you think your car is in the snow, the weak link is always the person using it.

And I drive an 89 civic wagovan, and these people are too afraid to drive their focus or escort...
