the random blurring of the pen strokes kept me thinking that my bit-rate was plummeting

You know this class is hard when he says “a few of you actually got the answer!”

My expectation is rarely that my students would get a question 100% right, though some will! There are too many tiny places to make errors. Heck, I usually have to fix my key after I start grading. It's not that I don't know the physics! It's just that all this algebra creates so many opportunities for careless errors. Be vigilant, of course, but always ask yourself if you understand the physics. If you do, you're okay (even if you're error prone.) If you don't know why a sign is negative instead of positive (and you error is one of understanding rather than careless), then you need to study more. When my students understand the physics, they will get A's even if exceedingly few will get 100's.

Man I just wrote an entire essay around a similar subject and this video would've saved me a whole bunch of time. Genuinely phenomenal explanation, the best I've seen yet.

Thanks for the feedback. One day I'll tighten these up, but it's good to know that they're useful. I know that when I made it initially, I was really struggling to understand where the squared came from. One r made sense, but I couldn't wrap my brain around the second one. (I'm sure my college prof must've proved it for me, but I couldn't remember. I suppose we need the proof when we're ready for it!)

Sir can you make a video on how can I calculate magnetic field inside a solenoid on it's axis with using complex integration at any point on axis?

@waynewagner2255 8 ай бұрын

I would love to, but I do not have the time at the moment. Can you send me the problem? Maybe I can work it out quickly if you like?

28:00 why you did't add th weight of the nozzle is't that also affect to anchoring force ?

@waynewagner2255 9 ай бұрын

For the part of the problem prior to 28:00, I have done a FBD of the water (and not the nozzle). As such, the weight of the nozzle is does not act on the water so it is not included. This problem can be solved quicker by doing a FBD of the CV of the water and the nozzle at the same time. I did not do this here, though, because (I think) I wanted to make the point that you can draw the FBD of whatever system you want, as long as you keep track of the forces (and reactions).

in given sead that one side is filled 4m deep with acetylene correct ? in that case your gamma in right side is not correct and equation becomes quadratic and height of water should be 3 meters aprox

@waynewagner2255 9 ай бұрын

The gamma used on the left was gamma_w = 9810 N/m3, The gamma on the right was gamma_acetylene = specific gravity of acetylene*gamma_w = 0,38*9810 N/m3. You can see this done right around 31:45.

come on man pay attention to what you are teaching you messed foot with meter at 27:10

@waynewagner2255 9 ай бұрын

Fair enough. Obviously (I hope), I did not do these with a ton of production. I messed up a distribution of a negative sign and accidentally wrote m instead of ft.

you really messed up man from about 20:00
