About 2h and 25minutes. Is that answer satisfying?

The answer is to the term "tyre slip angle" Have a look here https://en.wikipedia.org/wiki/Slip_angle and here https://suspensionsecrets.co.uk/tyre-slip-angle/ You could also find usefull the Ackermann steering geometry: https://en.wikipedia.org/wiki/Ackermann_steering_geometry

In fact, pump motor output power P2 is proportional to the cube of flow, for a given network, without height difference, if you vary the motor's rpm. There is no reason to suppose that the flow head will be divided by 2. A more logical very first approach assumption to start with would be that...

You could start with some approximations (even extreme) and see how safe you are. Then you can go to more realistic assumptions. A good (and somewhat realistic but not necessary from the safe side) start is to consider an effective zone of the welding assuming a 45 degree angle from the hole to...

It is very difficult to assess the contribution of bolts 1,2. If you want the structure to be rigid, I recommend to ignore bolt 1,2 and just calculate bolts 3...6. The surface connected by bolts 1,2 develope some friction, which in general is small. In order to calculate that friction, you need...

You can also use strain gauges to measure torsion but there is not need to mention that at this discussion. (I mean that you are a little off topic, by my point of you, as the above message is completely irrelevant with the discussion as far)

If anyone interested, please have a look at the following somewhat simplified image, regarding reinforced concrete https://i.ytimg.com/vi/xn69MLh7Pl0/maxresdefault.jpg

Hi! The above statement does not apply to every material. A very good example is concrete.

The contact surface, is not linear, but somewhat flattened. To make it more simple to explain, let's suppose that the floor is undeformable. Supposing you stand on the moving object, the wheel points should have a relative velocity u = ω * R. The R of the wheel point in contact whit the floor...

This deformation it self does not produce rolling resistance. The resistance is produced due to internal damping of the materials. The vertical forces behind the wheels are a little smaller than those in front of them. So a little braking torque is produced. The damping I mentioned above depends...

Ohhh, i didn't noticed that. I any case, it is just a variant of the same question.

I would prefer to express it as Radial external pressure differences. In other words, among others, It is the boundary conditions that determine the movement of the droplet, or of the parts of it.

In any case, moon and marble will move with the same acceleration towards earth That's true. You would also notice tide and wind currents-atmospheric pressure changes by just approaching moon to earth

Yes, cavitation phenomenon increases with pump speed

The answer is at my post above
