why physics when you are a truck driver 🤣🤣🤣

ReinkDesigns@reddit

I mean there's no correct answer. A is stopping from 70 because a Miata pulled out Infront of them they are currently at 55mph, B Is cruising as 55mph because the miata doesn't know where the gas peddle is, and C is trying to get back up to 70 after flipping off the Miata driver who finally after 40 miles got to their exit, currently at 55mph

iHasPinny@reddit

I drive milk tankers for a living, id say B is at the fastest speed costing down the highway it tends to settle

[-]

NoDakSniper@reddit

All of them could be going the same speed

[-]

FilthyNasty626@reddit

Depends on how hard the fuel pedal is pressed, grade of the road and gross weight of the vehicle. Now if you are talking about stopping distance (inertia) definitely #1 will go further.

[-]

DamitKenneth@reddit

If all the trucks are in motion and we are just going by the fluid in the back of the tank. Its B. Top tank is breaking Middle is in motion at top speed Bottom tank is starting up.

[-]

JOliverScott@reddit

I answered this on the other post in /theydidthemath and it's B at the moment shown. A was probably getting a boost from forward surge a moment ago but now the tide is receding and C is feeling the drag of all that weight collecting in the rear of the tank.

[-]

Dindu______Nuffin@reddit

That's not the answer at all tho. There is nothing to indicate which one is going the fastest. The only indication of anything at all in acceleration, deceleration, or steady speed. Or possibly uphill, downhill, flat road. Any one of them could be doing 2mph and any one of them could be doing 90mph.

[-]

SeaRow556@reddit

Isn't this to demonstrate the flow of liquid during a stop a is immediate b is the back splash/transfer of momentum to rear and c is the rest of the liquids momentum sloshing back?

[-]

TwoToadsKick@reddit

What if b actually just finished coming to a complete stop

[-]

hesslake@reddit

Fill it to the dome liquid doesn't move

[-]

Stinkybutt69420yee@reddit

Heavy lol

[-]

Bogey01@reddit

No scale on the back roads!

[-]

deadpat03@reddit

C realized he was being passed while watching TikTok and is accelerating to stop B from passing him while A is getting on the brakes because the far left lane had a Jeep Wrangler doing 1.5 mph faster than B but he turned his air conditioner on. So the answer it was A. Now it's B but not for long. So C will be the fastest.

[-]

InvestigatorBroad114@reddit

Truck C obviously since it’s a smooth bore tanker the liquid surges to the back of the tank

[-]

Spankpocalypse_Now@reddit

Unless you’re going down hill, then A will push you faster.

[-]

InvestigatorBroad114@reddit

Correct

[-]

Cfwydirk@reddit

A tank trailer with no baffles inside?

A) is on the brakes.

B) is in stop and go traffic.

C) is accelerating

[-]

Choice_Manufacturer7@reddit

Many chemical trailers are smooth bore. Makes it easier to completely sanitize for the next load to prevent corss contamination.

[-]

AM-64@reddit

Milk trailers are like this too

[-]

Cfwydirk@reddit

Not even baffles to slow down sloshing?

[-]

Parasite76@reddit

Some food does not have baffles either. Impossible to clean enough.

[-]

Inside_Ask_5305@reddit

Zero food grade tanks have baffles.

[-]

Parasite76@reddit

I’m aware of none but I figured I’d be vague because well weird exceptions exist

[-]

FatManLittleKitchen@reddit

Lol

[-]

paulbunyanshat@reddit

Baffles are fantastic if you haul the exact same product over and over

[-]

Questionoid@reddit

Nah. You can haul milk over and over and baffles wil get you cheese.

[-]

paulbunyanshat@reddit

Excellent! I love cheese!

[-]

Choice_Manufacturer7@reddit

No, just a smooth bore tank.

You will learn to drive different with one.

[-]

danDotDev@reddit

Nope

[-]

syncsynchalt@reddit

Yeah, these only show the acceleration, the velocity could be anything.

Dang it this is just engagement bait to snipe physics nerds isn’t it.

[-]

Dead_Namer@reddit

Exactly, C is likely to be slow as the acceleration is hard but the other 2 could be anything.

[-]

UltraViolentNdYAG@reddit

Ya, it would be level at 90mph on a flat level road over time. These could be grade issues too, not just accel/decel.

[-]

HurriedLlama@reddit

None of them are moving. A was moving forward and came to a stop. B has been stopped for a few seconds. C was in reverse and came to a stop.

[-]

Sarcasamystik@reddit

I saw someone post A and C could be the opposite if the truck was in reverse

[-]

Flat-House5529@reddit

The wanker that originally tweeted that obviously failed physics in school.

[-]

AndromedanPrince@reddit

are we on a grade or flat ground?

[-]

Spankpocalypse_Now@reddit

Why is this comment downvoted. Incline absolutely effects surge.

[-]

ConsequenceSweaty241@reddit

C 🤣🤣😔

[-]

ausernamethatcounts@reddit

Does it have a Cummins or a Caterpillar motor?

[-]

bobsanidiot@reddit

Impossible to tell. But the bottom one is accelerating and the top one is decelerating.

[-]

Questionoid@reddit

I’d say this is the closest to accurate. Speed has little to do with the inertia, or lack thereof, of the load. But the changing state of acceleration and deceleration sure does.

[-]

AndromedanPrince@reddit

ding ding

[-]

Tricka6@reddit

Speed doesn't matter here it's the acceleration/deceleration. If you get cruising at 60 mile an hour on flat level ground the load would balance out evenly in the tank

[-]

smileypalmer1978@reddit

B , everything would be mostly level

[-]

TwoToadsKick@reddit

What if b is stopped

[-]

TrollSlap619@reddit

C

[-]

Tallon_raider@reddit

Speed doesn't affect the distribution of the liquid in a tanker at all.

[-]

quackl11@reddit

I was watching someone hauling water on their truck today the water can be in any spot just due to it slashing around accelerating, decelerating constant rate

Impossible to tell the answer

[-]

Puzzleheaded_Ad25@reddit

Truck C… simple. Walk with a water bottle. What’s it do? Water gets pushed backwards. Constant speed and the water will be level. Braking or stopping or slowing the water continues its momentum and goes forward.

[-]

BingBongFyourWife@reddit

A could be hitting the brakes to slow down from going infinity miles an hour though while C is accelerating from going five

Like a perfectly level tank could indicate 0mph held steady or a million mph held steady
