That's 5 hours a day that you can't spend at working, resting or on leisure. Intuitively, one would expect this to have negative effects on productivity and life in general, the research seems to agree: From https://hbr.org/2017/05/reclaim-your-commute (links to studies in article).

A gear motor (geared motor, gearbox motor etc), something similar to this. Though, That would be run outside just outside it's RPM range and the power rating is probably a bit low (And of course the gearbox needs to be backdrivable - so no worm drives) but I'm sure an appropriately specced...

I would put a 5/8" socket on the shaft then run a prony brake on the socket. You could hack something simple like this together in an hour. Or buy a basic version off the shelf. If you want to load up the shaft indefinitely then a cheap DC gear motor run as a generator will work. Vary the...

They are convex, concave and mitre (or straight) welds on a lap joint. The most important difference is the effective throat. This should give you some search terms for your textbooks/lecture notes/Google.

You can buy a digital temp controller for just a couple dollars. or for a few more. Just find one that'll met your specs.Many have an autotune function, which works in the same way as the autotune feature in the marlin firmware found on most 3d printers. So you don't even need to know how to...

Experimentally and analytically.

You're welcome.

The pull force creates a moment about B so the downward force at A will be greater than 100. You'll have to assume C is directly below B.

Some of the force on the gate is supported by the non hinged end (at A). Taking moments about point A is probably the quickest way to find the force on the hinge.

The traditional solution is to build up rather than down, why would we change?

Another issue is that manufacturers generally state peak engine power as measured at the flywheel. After losses in a complex 4wd drivetrain like in a Veyron power at the wheels can be 30% less.

You can watch an analogous experiment at 7:45 in this video:

The pressure differential is absolutely essential information. You can use Bernoulli's equation and the continuity equation to solve for flow rate.

Well domestic fridges with glass doors are already available so presumably they're desirable to some consumers. Take a closer look at the supermarket next time, all the fridge doors are already double glazed. If they weren't, condensation would obscure the products and defeat the purpose of...

Yes. FDM parts can never be flat so light will always be defused. There are post processing techniques that help: http://taulman3d.com/t-glase-optics.html
