Technically the galaxies could not be moving at all if space is expanding so chances are they are not moving faster than light since that would break the laws of physics.
"Metric expansion is defined by an increase in distance between parts of the universe even without those parts "moving"...
you don't need to know the torque because the torque of the one end of the seesaw should be equal and opposite to the torque of the other just like you have in your one equation. You know that your total length of the seesaw is 5m so set up a second equation and then you have two equations and...
ah ok, I guess that makes sense. I saw that they calculated Reynolds number and that the values suggested that the flow was turbulent, are you saying that they calculated them incorrectly?
Sorry for the confusion, the application I would be using this for would be for a decreasing area, nozzle...
Yea, according to what they were studying they were trying to look at turbulent flow so it would make sense that they would try to induce that however you are right about how it seemed as though they had no way of controlling the overall flow.
Would you say then that their test looked at mostly...
Yea I know that, the thing is that there are additional losses associated with a change in cross section shape that I do not know how to account for. I would use the Bernoulli equation but would need to calculate the head losses a different way.
So I was trying to understand how fluid flow is affected through a transition duct when I found http://nopr.niscair.res.in/bitstream/123456789/152/1/IJEMS%2014%281%29%202007%2012-18.pdf that was done. In the study it was noticed that there was a dramatic drop in velocity near the end of the...
The reason why they do it in just the locations of the bearings is normally to act as the actual journal of a bearing surface but if what you say is true about them not slipping at all then it probably has something to do with strength or stiffness. What are the shafts used for, what loads do...
well the only ways that I see to calculate the volume of water is either know the volume of the container and use a float like thing as described which you don't want to do, or you can determine the weight of the water which you can't use a scale for. Ultimately you may just have to suck it up...
I'm not sure if you can do this or not given what you described but could you use the concept of buoyancy at all? This boat is going into water correct? If you have the dry weight of the boat then technically the buoyancy can give you the wet weight and from there you can get the volume of water?
Depends on your understanding of programs like Solidworks, Inventor, and ProE. There are a lot of companies right now that really really want people that can use these programs well, if you can convince them that you are very savy in some of these programs then they might be willing to take you...
One thing I think you could do but it seems very janky since it would be color coding each point individually (technically). You could have MATLAB calculate the range of your values and how many values there are and then relate each point to the intensity of red. For example you have 100 values...
I guess this is a better way of explaining it and I realized that I was misleading in my first message, sorry. A limit only exists if there is a continuous function. Since your equation is not continuous at that point then a limit does not exist.
In your example the limit as x approaches 0 is ∞, that's what the limit equals. If you were to plug in 0 into the equation you would get undefined since you can't divide by 0. The limit and the actual value are two different things. What it's really saying is that the limit is not approaching...
Your teacher is very misleading if that's what he said, the sheer volume of water does not always affect the pressure. The height of the water is in the equation, pressure changes with depth. As you get deeper underwater there becomes more and more pressure; however, if you make the volume of...
