25 YEARS SAFETY EXPERIENCE ASK ME ANYTHING

Current or Former?

Do you know that we know more than you may think we know?

How long did it take for you to realize that drivers are the Good Guys?

 

Most sobering moment, checking out an experienced guy. Coming from I-80 to the NJ Turnpike and he points at a spotof damaged on a huge concrete structure and says "I did that!" He didn't 'stick' there anyway....

 

I can actually answer that question, as I was a Physics major in college (unfortunately didn't finish 3rd year)
Anyway, you're on the right track to wonder such a thing. It's a great question. Answer is a couple things are involved. Mostly, it is the fly's tiny amount of mass that allows it to compensate for the rapid change in speed without smashing into the windshield. If it was the microwave sitting on your bunk, well, that's a different dilemma! Also, when you brake, the fact that the air in your cab brakes with you, aids the fly with compensating. The Air is a gas and doesn't behave like, say a glass of water (or whatever other liquid you'd prefer to be in your glass). It's tendency is to equally fill the space it has and have equal pressure through that whole space. If you had very accurate pressure gages in the front and back of the cab, when you brake hard, you would see a tiny difference in the Air pressure on the front of the cab, being more and the back of the cab being less. But, the difference would be very small as the air, having a very low mass, won't need much of an equal and opposite reaction from the braking force to compensate in addition to its tendency to equalize. The fly is within the medium of the air and uses the air resistance to help compensate. It's kind of similar to if you jump in a pool, the water will slow you down quickly as it provides a force acting against you. The air will provide the fly a similar sort of force, albeit much smaller. But, it does aid the fly in not getting smashed by the windshield. Ifmthe fly were in a vacuum, 1. It'd be dead, but importantly, it would smash into the windshield as it didn't have any medium to use to counteract the change in velocity.
There, clear as mud!!!!

 

25 years? How do you count that high?

 

By 2's

 

You must have 26 years of safety experience. I’m coming to you with all further questions. Lol

 

If my girlfriend is in a really bad mood and I smack her on the rear end is that safe?

 

BTW

My favorite scene with Ginger was when she was a secret agent.

She said I'm secret agent 0036.

The guy says, 0036?

She then takes off her trench coat and she's wearing a bikini.

He then smiles and laughs, and says,
oh oh, 36!

 

Like most safety departments, lip service, and has decided it isnt worth talking to the plebians
