From Wikipedia: Ionizing radiation is generated through nuclear reactions, nuclear decay, by very high temperature, or via acceleration of charged particles in electromagnetic fields. Natural sources ...

I don't design HPUs, but I'm a mechanical engineer now and have previous experience with them. I would guess that the oil viscosity is the primary driver for its minimum temperature. Below the rated ...

Electrical impedance and acoustic impedance take the same form mathematically, so I personally find it super helpful to think of electricity in terms of acoustics. Stand in an open field and shout. No ...

I'm reading company training materials and I don't understand a few terms. So I'm sure that alephzero's answer is probably correct, but you're reading company training materials. Acronyms and jargon ...

How do I fixate the rod onto the ceiling without stopping it's rotation? With a thrust bearing. A conventional bearing supports radial loads; a thrust bearing supports axial loads.

Ideally, I would imagine there would be sufficient material in the burner and the fan speed would be the only thing to modulate to regulate temperature. If that's the case, then I would have the ...

There's no uniform radius of curvature with your shape (c) so you can't have a closed series of rigid linkages that's capable of moving around the track. You can use a flexible link or cart as a ...

There's two different "shut off" methods: showing a black screen and actually powering off. To show a black screen, the backlight stays on but none of the pixels are energized. Light that gets ...

If the load is evenly distributed, then double wheels would be something like: [Mg/4] [Mg/4] [Mg/4] [Mg/4] \/ \/ \/ \/ [tire] [tire]--------------[tire] [tire] ...

Wikipedia gives the reason for Mach 0.3 as due to the fact that this achieves ~5% change in density. I found a NASA page that describes (analytically!) the relationship. I cited the source, but I'll ...

I never quite found exactly what I'm looking for, but I did come close, so I'll post what I've got. If anyone ever does have a better answer, please post it and I'll accept that one as correct. The ...

I believe you are describing a charge pump. You don't give any specifics on what you're trying to do, though, so I can't really give meaningful feedback on anything else. Generally speaking, though: ...

Sorry I missed this over at Robotics. Your question is really unclear and you don't have a good diagram that helps it out at all. You say there is no gravitational field, there are no springs, there ...

I am having a really hard time following your setup. First, you have the x-axis as the vertical axis, and the y-axis as the horizontal axis. Is this correct? And then there's a... surface?... when x = ...

Can the difference in damage be attributed to much different speeds of the two vehicles? Which speed? If the cars hit each other, then there is only one speed that matters - the speed of car A ...

is it possible that the torque generated from the momentum of the beam I'm going to stop you right there. Momentum doesn't generate torque. Momentum is moment of inertia times speed. Torque is moment ...

Winch the bucket down, fill the bucket, then winch the bucket up. You're not trying to move this some huge distance, and it's not some huge reservoir to move. A pump is overkill. You could, ...

That is quite the wall of text. You don't need to rewrite an entire academic paper to ask a question (please don't). You failed to show what it is you thought you were supposed to get or what you ...

Source control isn't going to fix your problems. Let's review: We don't have a way to allow multiple people to work on different components of a model simultaneously. Why do you have multiple people ...

This.... this is the content of most of a semester on digital signal processing. You said, "I found [a book on signal processing], but it is a book of 700 pages with plenty of math." Well, yes. ...

Where's the rest of your block diagram? It looks like you have a polarity problem - You give a step of +1 and your pos_meas_Hinf goes down instead of up. Nothing you've shown in your diagram looks ...

According to the Wikipedia entry: [The earthquake] produced maximum ground g-forces of 0.56, 0.52, 0.56 (5.50, 5.07, and 5.48 m/s2) at units 2, 3, and 5 respectively. This exceeded the earthquake ...

Suppose Frame 1 is a world coordinate frame and Frame 2 local robot frame. The thing that's a little confusing here is that when you transform from Frame 1 to Frame 2, you are saying that you want ...

I can't tell what you want. A combination of a part and forming tool What? I want to drag this part into a closed sheet metal area and the holes for the nut should be created automagically ...

The ideal gas law says: $$PV = nRT \\$$ where $P$ is pressure, $V$ is volume, $n$ is the number of moles (molecules, basically) of gas, $R$ is the ideal gas constant, and $T$ is the absolute ...

How do you have an LQR with open loop control? I know that there would be these requirements if I were to implement a closed loop control A linear quadratic regulator is basically a multi input ...

One plate is lead, one plate is lead dioxide. Hand-waving a big: sulfuric acid dissociates in water, making a lot of hydrogen sulfate ions. The lead plate reacts with the hydrogen sulfate to make lead ...
