Oversize takes out I5 bridge in Wash.

Oh please.......I'm looking at this from the perspective of an owner....Ever hear of this word -"EXPOSURE"?

How about this word-"LIABILITY"?


I wonder if some drivers know their meanings sometimes......

 

That's funny! I'm nearly 80k empty!

Please don't tell me how to drive, I highly doubt you have close to my experience!

I run 55ish. Let me help you with some elementary physics. There are 5280' in a mile, even at 55mph divided by 60 mins per hour = .9166 miles every minute. That's still 4840' per minute divided by 60 seconds = 80 feet per second.

At 175,000lbs (my average) on 9axles that is avg 19500# per axle compared to 16000 avg for your atypical tractor trailer. That is approx 22% more weight per axle, which means approx 22% less braking power. This is potential energy only and does not include kinetic energy, but that is advanced physics.

The idea of a 200' warning device is irrelevant. A 200' warning device even for an atypical 5axle is insufficient. If this is your idea of a fail safe, like I said, clearly you don't have an understanding of what you are commenting on.

 

Oh ok......Let me go check my CSA score........



































Yep.....It's still like your batting ave. here......


.000

 

55/MPH = 80.667/ft per second...couldn't resist it..

 

Nevertheless....The Driver still hit the bridge....It collapsed as a result....

Stop making excuses for him.....

 

Actually, my avg is 1.000. Everything I have posted is Fact!
Your exposure of yourself is becoming a liability.

 

Thanks for playing.....


So keep denying the driver you claim to know is not at fault...Even a little bit.....My my....We're in strange days when people can't assume responsibility for their actions.....

 

Personally, I think discussing these accidents in an open forum is a great benefit. It's probably not helpful to attack persons with different points of views as to fully understand the dynamics of such an accident is best served when many experienced drivers "weigh-in" (pardon the pun).

Regarding your ADVANCED PHYSICS comment, braking power MUST be calculated as JOULES and F(force)=M(Mass)*A(Acceleration), as a mass in motion WEIGHS MORE (requires more force to seek equilibrium) than the same static load. To successfully brake, all forces summed must equal 0.

Much in the same manner that 1lb on a 5' plank requires 5 lbs of force to lift Weight (1lb) * Arm(5ft) = moment lbs aka foot-pounds(5lbs).

My personal feeling regarding this accident is that many factors will be found to be contributing, and having traveled that bridge , many times (used to live in Mt. Vernon) I DOUBT if the single cause of the failure was the impact of the load. If that had been a new bridge and was struck in an identical manner, would it have collapsed? I don't think so.

So let's keep the string going' with one minor suggested formula change :

[QUALIFIED OPINIONS minus (-) [PERSONAL & CONDESCENDING ATTACKS PLUS (+) WILD ASSUMPTIONS] = GOOD TOPIC DISCUSSION

Ever wonder why the +/- 20% of bridges that are structurally deficient are not marked for the traveling public to see and decide whether they want to use that route??? That's the only crime I see that has been committed thus far.

 

Do you think before you type?

I have not said he is, or is not at fault!

I will heed my own advise and wait for the NTSB report and let the facts decide.

I have made ABSOLUTELY NO excuses for my friend. I have only stated SOME FACTS that clarify some inaccuracies.

Both he & I are highly respected men who absolutely take accountability for our actions, good and bad! Pay particular attention to the fact that he has fully cooperated with the authorities and was the first person to alert said authorities!

Will you be accountable for yours and admit that you've made assumptions you know very little about? I doubt it.

Believe me, I have not said all I know about this incident. We have had several lengthy confidential conversations, there are a lot of facts that have not been made public yet. Unfortunately, this will be old news when the NTSB report comes out, and almost nobody will care! The media sensationalism will have long since lost its luster by then, it will probably be a footnote story at the end of the newspaper.

 

My bad, I apologize!

ish is +/- 1% isn't it?
