Further research indicate coanda effect to explain the case of teapod. If it was with water the result would be the same. In conclusion i think i am being putting questions that are not essencial to this topic. But i have the problem of weight of the sheet of metal. If the weight increases we...
Well, i think that you gave me the facts. Water height vs capillary effect. But you dont gave a explanation about why this occurs. Why water have the ability to glue to everything that is on some range. Its the same with teapods, some spills other not. The ones that spill, albeit gravity, glue...
Reading your phorum give me some thoughts. If water seals the air, when the water trail ends the effect disapear. In other hand i think that the atoms of water have a tendency to being attracted to close flat surfaces. I need a explain about that. And if the tray is more heavy the effect is...
Like f1 cars skirts to produce ground force effect (or vacuum). My problem is that i use water and i want to know if the solid follows the water path. I remember staying at coffee and a servant put an aluminium tray on the table who was wet. The aluminium tray could slide on surface but to...
The two surfaces are glued by atmospheric air and some by water molecules. Some questions arise (I think). Water vapor is considered atmospheric air? What is the role of water molecules? Could we talk on atmons instead?
I red the article about 3 types of wringing. 1-air pressure; 2-pressure from...
I am confused.They are glued by atmospheric molecules or water molecules? And if it slides, it slides for the same type of molecules?. With carefully push of the solid object it will follow the theorytical wet trail?
Water like glue
This topic could have more meaning on a chemistry forum.
Firts of telling my doupt, i will inform you why i put this question. My goal is controlling an obejct more accurately.
I notice that sometimes a solid with plain face on a wet surface is difficult to remove. Besides it...
If you have a planetary gear system with a sun gear and to 4 planetary gears with one-to-one relationship and fitted on the interior of rear wheel of a bicycle, and sun the connected to the cassete (plates) of the bicycle, you will not gain force advantage?
Well, my knowledge of torque and power (horsepower) was much acquired when I bought a car. For instance, I had Alfa Romeo 147 that his maximum power was 118 hp at 6200 rpm. Now I have Peugeot 308 with slightly like more power (128 hp at 5500 rpm). it is useless to rev up or down that the maximum...
Hi guys, it’s me again!
Well back to basics. First, my apologies by my poor physics terms.
What I want to know is if like a windmill or animal traction mill when the force is applied in edge of the mechanism, we gain leverage.
If so, why so many machines use a central point of applying force...
Hi Lnewqban,I even speak about the angle of attack of the blades, and I have yet problems with the weight of the chain. I suppose the width of the chain could be smaller than length of the tip of the blades and independent blades angle. The length will be different, it must have the diameter of...
About using of a chain, remember that motorbikes use chains to transmit power to rear wheel, but yes could be malfunctions.
On applying the force in the edge of the blades, the early planes started with human help, who pull the propeller by the edge of a blade. I think this proceeding is...
Hello,
My first innocent thread.
I want to be clarified about a subject that it's hanging around me. Maybe is ridiculous, but I want to know if the force that I applied in center of the propeller (I think it calls "boss") is equal to force applied in edge of the blades to get it move around...
