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: ...

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 ...

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 ...

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 ...

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 ...

Mechanical designer here - how do you get an inside cut on a sharp angle like that? What tool makes perfect corners? You said, "On top of this plate I will mount four... bars of wood." So, if the ...

The datasheet for the device should always list a maximum or "stall" current. For this device, it's 2.5A. You can use that for a worst-case estimate of battery life by multiplying it by the amount ...

Dampers. Resistive forces are inertias (m), dampers (b), and springs (k), and the equation is generally written: $$F_{\mbox{applied}} = m\ddot{x} + b\dot{x} + kx \\$$ That derivative term - $\... View answer 1 votes There are globally accepted names for these positions, and they're even color-coded! If this is a really big issue, consider using port and starboard. This is used in nautical and aviation industries ... View answer 1 votes Torque,$\tau$, is required for rotational acceleration,$\tau = I\alpha$, and for viscous losses,$\tau = b\omega$. Here I'm using$\phi$for angular position,$\omega$for angular velocity, and$\...

I don't know for sure, but I doubt that would be the case because all of the E-Stop circuits I have worked with signal shutdown on the transition from high to low; this ensures shutdown even if the E-...

Acoustic impedance is very similar (mathematically the same as) to electrical impedance. When an electrical wave hits something with infinite impedance (like unconnected wires), electricity doesn't "...

I think you may be getting a little confused here. There is a fit tolerance, which determines how easy it is to insert and rotate a pin in a joint, and then there is machining tolerance, which is how ...

I feel like I say this a lot, but it seems to be a commonly overlooked design spec. Torque is a force applied (orthogonally) at some distance, but torque is also moment of inertia times angular ...

$$\tau = 500 \mbox{Nm} \\$$ $$\tau = r \times F \\ \tau = |r| |F| \sin{(\theta)} \\$$ If the lower left angle is $43^{\circ}$, then the top angle from the bar $r$ to vertical is then $180 - 90 - ... View answer Accepted answer 1 votes Sure. CO2 cartridges are made of steel and hold 850 psi. You want to use brass, which has 80% of the yield strength of steel (200MPa vs 250MPa) to hold 35% of that pressure. Not to mention the fact ... View answer 1 votes You are correct, you can't disassemble a valve that's currently isolating system pressure. This means that you have to isolate the system (at least) one valve upstream of the valve you intend to blank.... View answer 1 votes I don't think you're going to find an answer that meets the intention of your question as I read it. It takes energy to convert water from a vapor to a liquid. Some materials (minerals, sugar, etc.) ... View answer 1 votes In Inventor, you can select the location ("datum") you want to use for referencing where you intend the bend to be located. First, make a sheet metal part: Then, make the base face whatever you want ... View answer 1 votes Your comment, "my interest is more whether we can make machines waste less energy due to a lower friction and how such things can get realized" provoked me to respond: On an initial thought, a fluid ... View answer 1 votes You are correct, blanks are installed at a pipe flange where two runs connect. Typically you break the joint and pry the flange apart to install the blank, but this can cause problems if/when the ... View answer 1 votes Couldn't you just define$y(t)$and be done? $$y'(t)=u(t) \\ y(t) = \int{u(t)}dt \\$$ As long as the system is controllable, as defined by the controllability matrix$M$being full rank, it doesn'... View answer 1 votes I don't think there is a formula. For metals, at least, these values are all derived empirically via extensive testing, such as the Charpy V-notch test, tensile testing, fatigue testing, etc. ... View answer 1 votes 20cm diameter gives a cross sectional area of$\pi r^2\$ or 314.15 cm2. 8cm diameter uses the same formula for a cross sectional area of 50.26 cm2. The free space around the float in which the water ...

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 ...

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 ...
