Thank you very much for your time. I do agree with you that I need to do most of the work which I am trying to get a solution right now. But sometimes, the views from experts could widen my ideas and for which i can get my work done in a relatively better quality, also saves time. XD. Just...

Thank you for replying. What you have said above needs image processing and it is hard. what i have forgot to say is that the project is supposed to be "low cost" which limits how much resources we can have/spend on this project. our design is actually on the side of the pool, plus the...

Hi, I am a final year student whos doing engineering degree. My final year project involves tracking the speed of a swimmer inside a pool. The current problem is that i don't have a good way of monitoring the swimmer's speed, which needs to be quite accurate(centimeters). Due to different...

cover up rules? equating coefficients?

f=ma as pongo mentioned probably start with a free body diagram which identifies the forces on the body u r interested in.

Thank you cyrus. I know strouhal number and it only tells information providing that vortex shedding does occur. But sometimes when making an engineering design, hmmm... don't we need to take vortex shedding into consideration? instead of making a prototype and see if there's presence of...

i mean to take out the line where u cout the # from ur original code. and btw, don't have vs here, so can't really run ur code. can u please post up the outputs? both original code and the one u have atm?

hmm... its like really basic. just get familar with kirchhoffs v and i law. u'll be fine

try put a if condition insdie the do while loop instead just cout outside while loop. could use conditions like if j = len -1, then cout the #

try move the g/s over to the left side of the equation. s3Y + sY - g*s-1 = X. Then do the transformation(use the table).

treat the 1.5R and R as parallel. then in series with the 0.6R to get the overall resistance. current going through 0.6R = voltage/overall R. Then the same current split into the 1.5R and R, calculate.

With given object dimensions and speed moving inside a fluid. How do i decide if vortex shedding will occur? It is sometimes obvious just to look at the speed and dimension and say it will not occur as its going too slow or vice versa. Is there formula or some mathematical criterion to...
