Those darn Narrow Roads...

[hobbyfarm]

Guys,
no matter how many cool, functional features the engineers build in to these things everything is at the mercy of the bull-headed decisions made by the person just road-raged /forums/images/graemlins/mad.gif into doing something stupid or dangerous.
It don't matter if you're from Guam or NewYork or if it's a truck or a table saw, when there's baggage on the mind, stupid things are the result.
It's kind of funny - in cartoons they like to draw the characters with a little tornado over their heads when there's some sort of irritation.
I'm trying to learn to control my tornado! /forums/images/graemlins/wink.gif
(it's too expensive not to)

When we first bought our F-250 we had a bus come thru and nail the drivers side mirror as we were parked on the shoulder. It folded forward but shattered the glass and ripped the little motor out and it dented the fender about the size of a rain drop. So I guess it all depends on how they catch the other mirror as we folded our back out and still used the lower glass that didn't break till we fixed it.

Just think about your stubbornness....... another couple of inches, and it would have been called a head on collision, and there is no telling how either of you would have faired. Two vehicles traveling at 30 MPH, headed toward each other, when they collide, is like each vehicle hitting a stone wall at 60 MPH.... that hurts real bad!!

Well, I would not really call either as Ford or a Dodge a stone wall, but the results nonetheless could cause some major injuries.

Actually, two vehicles travelling at 30 mph run into each other is like hitting a wall at 30 MPH.............think about it........

OK, now I'm trying to understand this better. Two vehicles traveling 30 mphs towards each other have a closing speed effectively equal to 60 MPH. Thus, I say the amount of energy transferred as far as momentum is concerned is 60 mph. I suggest it is not like hitting a wall at all unless the wall crumples similar to that of a Ford or Dodge truck. I would rather hit a truck at 30 mph then a immovable, non collasable solid wall. Correct me where I am wrong. /forums/images/graemlins/laugh.gif

_RaT_,
Sorry dude, plain physics. Mass * Velocity. It don't make any difference what you hit, the math don't lie!

BOTH WRONG!!!! /forums/images/graemlins/grin.gif

Actually you would START your calculation with the effective closing speed of 60MPH, but then you would weight the "felt" impact of each vehicle based on which one is heavier. i.e. if the ford is heavier the "felt" impact will be less.

Math don't lie but there are many variables that add to the equasion as well. One is how much energy would the trucks absorb and disipate as opposed to the stone wall. The size of the wall would mater as well. The actual materials in the stone wall would matter too.

See what you started Junkman!!!! /forums/images/graemlins/grin.gif /forums/images/graemlins/tongue.gif

I thought that after I got out of school that I'd never see another story problem again. That is 2 things that I've been wrong about. /forums/images/graemlins/crazy.gif
