I have never seen these lines, the blinds are installed for approx. 4 years now. It is the only time I saw this.
I will get back to sending more pictures!
"Question for YeeHaa: Is that effect reproducible enough that you can visually sight along one of those rays to determine the source? I hope...
Hello all,
Wow! thank you for the huge amount of replies.
In a lot of replies I read some doubt about my sincerity but believe me (on my pretty blue eyes): no photoshop, no cheating. The pictures were taken with my Galaxy S8 phone and were uploaded straight to this forum (shared via mail).
I...
Thank you for the replies everyone!
Some more details and pictures:
No glass beads. However there is "light dome" which is above our bycicle shed. If you look in a straight line from where the lines originated you do not see the dome. It is slightly to the left (see second picture and sketch)...
Hi all
Today I came home to find very discrete lines of colored light on my living room floor. Can anyone help me to explain this phenomena? I am familiar with dispersion but am wondering how the combination of glass and blinds is creating this effect.
When I rotate the shutters as you can see...
Hi all,
First to clarify: this is no homework question. I am working on a construction and am really puzzled about the following problem.
I need a spring to hold an object in place during sideway shocks.
I am really puzzled about the fact if friction helps one or two times. In other...
The motor is 'hanging' on the wooden plate, meaning the brackets are on the same side as the motor shaft. So the rear side is facing down vertically. Microstepping is not an option since material has already been bought. The load is really light and starts perfectly when the motor isn't...
Hi everyone,
For a project I'm working on, I'm mounting a stepper motor against a wooden, round plate. This wooden plate is again fixed on a table. The stepper motor is fixed to the wooden plate using 2 metal brackets. The stepper motor itself drives a round object of about 0.4 kg that is...
I don't know exactly what you mean by "the premise being squirrelly", but I'm trying to create a simple robotic gripper for a project I'm going to start at home. But since all robotic grippers without joints have limited capabilities, I'm leaning towards a jointed one, but preferably without...
Hi,
In a small mechanical application i have, i want an electrical motor to drive a spur gear, and from the moment the spur gear encounters resistance (it stops completely), i want the same shaft from the motor to drive a second spur gear (which was NOT spinning at first, it starts spinning...
That is more than clear to me.
This is exactly what is confusing me (see my original question). Everyone always says: a pump doesn't create pressure.
Well you say now that the pump pressure output is 100-250 bar...
I understand that increasing load will increase the pressure (basic math...)...
So basically, when more load is put on for example a cilinder, the motor driving the pump will create enough torque for the pump to overcome the working pressure?
Does this mean the output pressure of the pump will always stay a bit higher than the atmospheric pressure (relative to the load...
That only confirms what I read and understand...
Still didn't answer my question: when there is a load which causes a pressure of 50 bar, the pump will still generate no pressure and will merely cause flow?
Hi everyone,
I have been messing around studying Hydraulics on my own, but I can't get round something. The following things are things I concluded after reading books, sites, ...
- The pump itself doesn't generate pressure, but when there is a resistance in the circuit, there is pressure...
Sorry for the really late response, but I was on holidays.
I read all your replies, and I have to agree with this the most:
"The OPs question is not stupid because there seems to be a problem with the teaching of electricity starting at the most basic levels that hasn’t been addressed and is...
Hi,
Maybe this is a stupid question, but I've been wondering about this all day.
In my book, they only explain the isolation transformer really brief.
As far as I understand, the main of the transformer has a neutral which is grounded, if you touch that, the current will flow through...
