3AM TOT: weight-bearing wheels

 I start writing an intro for this and I'm stopped by all the math and engineering.
If you're so good at math, why do you put teeny wheels on enormously tall very heavy equipment?
The designer of a parking lot wasn't thinking about carts when he designed that gentle slope.

Well anyway, the cart with the theoretical large wheels, and the expensive bearings, would roll away too easily, hit something and fall over ruining Thousands of dollars and your job, and you might even get a spot on youtube from an unhelpful cameraman.

My patent-pending design with the large wheels, needs bearings, sure, but it also needs variable brakes.

Dead-man brakes (Handles you push to progressively ease the cart into motion.) let go, it stops.
Push,*slowly*, and it eases forward.

Buuut no, you'll keep putting those miniature metal wheels that make a person use a ton of effort to move a couple feet, and if it should hit an extension cord,

it falls over!
Small wheels in factories are better, I just don't know why.

Rant mode:

You're a pedigreed engineer, you know this stuff, but you do it anyway

And don't ask "Reddit,"

They'll get all snarky.

Panic-buying fat people at 2pm vs yogurt-shoppers at 6AM, I an NOT talking "Shopping carts", bless their hearts for coming up with general-purpose transportation. 

Or, moving a couch down a steep hill, once every ten years...

No, *factories* should have decent equipment you could use, unless it's a gargantuan factory with hoarders requiring a chit (an MRO)
