Thank you! I think that thanks to you, I found the answer to my question. The problem was in the field of geometry. When developing the design of the generator, I considered this process, but I made a wrong conclusion. I thought that if the final positions of the points were the same, then the...

Thank you! Indeed, the points do not have an orientation or direction of observation. Only their final position and trajectory matter. In fact, this question is related to the observation of the electric and magnetic fields at points B and C, as well as at point A. The figure below shows the...

Good afternoon! Thank you for your comment! I will try to explain the question in more detail. Points B and C are highlighted on the blue circle. Point A is located next to the circle (Fig. 1). If the circle rotates clockwise, then points B and C rotate simultaneously relative to point O. As a...

Two points are conventionally highlighted on the blue circle. They are represented by small circles. The arrows indicate the direction from the center of the circle to the selected points. There is a point A next to the circle. Option #1: Point A is stationary. The circle is rotating. When it is...

Good afternoon! I would like to ask for your help with the following question. Am I correct in understanding that the rotation of a circle regarding point A and the rotation of point A regarding the circle have different relative trajectories?

Good afternoon! It seems to me that you were hired for a reason. Letters of recommendation are not given for nothing. The interviewers know their stuff too. You probably have wings, but you just haven't spread them yet. I can give you the following recommendations. 1) The success of any job lies...

Good afternoon! The link below contains a description of the wind turbine. It seems to me that it has some disadvantages related to operation. Such a turbine has a large area. To hold it in a gale-force wind, you will need a very powerful support. In a classic turbine, the blades are mounted...

Good afternoon! From the course of hydraulics, which I studied 22 years ago, I remember for sure that the full pressure of the water acts on the dam at 2/3 of the depth. It seems to me that your model may have similarities to a dam. Perhaps it makes sense to study dam calculation methods in...

I'm sorry, but it seems to me that in such a design there will be a vertical component of the force that works to bend the rod. As I understand it, it is not by chance that a support element is used in such structures, which is located diagonally. The force of his reaction is directed towards...

Probably need to do something like this.

It may be necessary to move the actuator to the point indicated by the circle and install it on the hinge. When the actuator stem is fully extended, it can be easily deflected to the side. I sometimes design such drives. They only work when loaded along the axis.

As far as I know, the actuator stem is not designed for lateral loads. It is intended only for loads whose force is applied along the axis of the rod. This is a linear actuator. In such a situation, you can try installing a roller support (in red). Or change the kinematic scheme of the...

Good afternoon! It seems to me that first of all it makes sense to understand why the drive lever is lowered. Perhaps the reason is mechanical backlash. If these reasons cannot be eliminated, alternatively, you can try to extend the lever more (or move it closer to the axis of rotation of the...

Good afternoon! If you need a calibrated leak, you can try using a permeable membrane or an air filter as an option. In the simplest case, you can make an air filter yourself if you press the required amount of filter material, such as cotton wool, into a suitable tube. This way you can get the...

Good afternoon! The low voltage in the Faraday disc is not related to the use of rings or brushes. The rings and brushes provide quite good electrical contact. The low voltage in the Faraday disk is explained by the principle of its operation. In such a generator, it is impossible to apply a...
