How to design a Non-inverting amplifier (theory + Multisim simulation) #amplifier
in this video we show the derivation of non inverting Amplifier theory for an x times amplification. After derivation we validated the theory with Multisim simulation of the non inverting amplifier. The Multisim simulation is a free online simulator that you can try to understand circuits. There are many other videos in my channel and circuit playlist for you to try. #circuit_simulation #multisim #amplifier #noninverter

whats the ideal mechanical advantage?
Just as a note, your experiment has a flaw: you are not measuring the actual mechanical advantage. The reason for the worm to start rotation so late is that it is engaged in 'static friction'. Every time you add a weight, you should rotate the worm a nudge to free it from static friction. If it doesn't continue the rotation, then add another weight. This can be also stated as the reason that the mechanism suddenly falls at great speed instead of a steady rotation, because there is too much weight on the worm side to warrant an equilibrium under dynamic friction. The difference between the measured mechanical advantage vs. the speed ratio is just too high with your experience, and the efficiency of the system is around 7% which is not justifiable by any means.
Hi sir what are the material required to this project
Hi, I'm an extremely visual learner. That being said I'm trying to visualize Christoffel symbol 'values'. So if I have a very messy curvilinear csys, how can I visually see or plot the coordinates of a derivative vector (one that represents the change in a given vector before and after being parallel transported an infinitetesimal distance dx. Should I... a) plot the coordinates of the derivative vector on the messy curvilinear csys (no idea how to do that) or b) plot the coordinates of the derivative vector on cartesian coordinate csys, aka known as the tangent plane...(I know how to do that). The issue is that a cartesian csys has a nice grid to count lengths of coordinates...but messy curvilinear cys is usually not represented as such (just four curvy lines. Where are my cury line grids!!! How do I make them. And, on the off chance that both of them are required, how do we size them such that they match? ie. If my cartesian csys has small grid units of one inch, but my messy curvy csys had them as one mile...you see what I mean. I feel like the metric tensor has something to do with matching them up. Thank you if you try to answer this. Rocky

Great Explanation!

Happy to help
Thank you very much! You saved me for our Long Exam.

I cant figure out why doesn’t the middle pulley start to move at fast
At first*
probably because the two hanging pulleys’ positions are dependent on their mass, since the rope is not pinned to them and allowed to freely rotate

please sir i want to know prosesure how to calculate discharge ?and how to calculate steps of hf ?
hi can ı ask you question?
Sure.
@@MohammadShafinulHaque I am an electrical and electronics engineering student and I have a project. I am looking for resources to do a project similar to the one I mentioned in the title. For this, I need to find the center of gravity with 4 cell loads and 4 HX711. I saw that you could do this project, but you did not share the codes in your video. Could you please share the codes used in this project with me? Thank you...
Hi Sir! For example 2, can you please explain about s-s node and d. whats the relation/term means as i couldnt understand clearly why we manipulate each term to get d min. Thanks vm!
The response time is the time during the car is still traveling at 44 ft/s, sot the total distance to come to a stop is putting final velocity in 2nd equation as zero and find the d, but the So is v*t that we need to add. So, for the 1st case 44*0.75 + 44^2÷(2*2) = 517.

I have 3 questions about this experiment 1. How and why does the thrust vary with depth? 2. What happens when the plane becomes fully submerged and why? 3. why might there be discrepancies between the experimental and theoretical results for the thrust?
at 720 m/s^6 a rocket can travel 1 quintillion meters in 1000 sec
It's a solid material
You can look at the top part of the specimen, can notice light coming through, not solid.
@@MohammadShafinulHaque Ooh, Thank you I just want to ask what type of pattern is inside
@@veereshhosmath341 we were studying the effects of printing orientation on tensile strength, we did 0, 90, & 45 degrees orientation.
@@MohammadShafinulHaque cool, we are also doing this in our college major project
@@veereshhosmath341 it's very interesting. Have fun.
It's not delta-robot. It's classic delta

can i pleas have a file
you are a brave man allah bless you.
May Allah bless you and guide you.
Let's say a wood has a FSP of 28% (which is the most common for green logs) and I lower it to 10% in a vacuum kiln. Will it absorb moisture again to reach the natural 28% ?
If a body is at rest at t=0 (it's position is equal to 0 so all of it's higher derivatives are equal to 0) and it moves, then it's position can theoretically be derived forever, because position changed so its first derivative is different from 0 so it can be derived, and this first derivative was 0 in the beginning, so it changed, so its derivative (position's 2nd derivative) is different from 0 So it can be derived, and it was 0 in the beginning, so it changed, so its derivative (position's 3rd derivative) is different from 0...
It can go on

So heating it red hot and putting it down in water or oil hardens it?

Why ?
what is the density of the quadrant?
Sir can I know why you add +2 after integrating, instead of t^2-1
It is given that when t=0 the initial velocity is 2 m/s, so when we perform integration, that gives us the velocity after time t, and we have to add the initial velocity 2.
Sorry I didn't get it too, the a is 2t-1 before integration! So why you put + 2 it's not clear for me :(@@MohammadShafinulHaque
@@BebaYoussef The integration gives the velocity from time t =o to t, but at t =0 the initial velocity is given 2 m/s, thus to get the actual velocity we need to add the initial velocity with the integration. Hope it helps.
@@MohammadShafinulHaque i understood now, thank you so much
@@BebaYoussef you're welcome
Where you from brother
Sir I have to design compound gear train 1:100 velocity ratio how can we calculate...if I am calculating 1:100 ratio the driver gear teeth are getting too much
You can do 1:10 step, and from the same shaft again 1:10 to next shaft, this from the first to the last shaft it will be 1:100. ua-cam.com/video/i_nNx5qvx8k/v-deo.html

I'm trying to power a water pump with the turbine but it isn't working, is there a reason for this and a way to fix it. I'm trying to use the turbine to power the Arduino using the Vin pin, and the Arduino will power the pump and the pump will flow water back to turbine and so on.
Seems like you are planning to make a perpetual machine. It could be that your major loss are high, how you are starting the turbine?
@@MohammadShafinulHaque right now im just blowing air into it, becuase i need to find a hose adapter, this powers the arduino on and if i use a plug the arduino can power the pump; its going to start out with the pump pumpning water up into a series of containers, the water will flow down through the turbine before going back to the pumps water source, i wanted to test to see if the turbine would turn the pump on first before continuing. when testing the pump with a plug powering the arduino i used a capacitor to recover the power, would that work?
@@_LKAT_ it seems the turbine is not generating enough for Arduino and pump both just by blowing. May need more water pressure to the turbine for higher rpm.
@@MohammadShafinulHaque Will eventually test it using the hose. How much pressure was needed to power the arduino because I plan to use the turbine in a hydroponic system with water flowing from the plant container. I fear that this wouldn't provide enough pressure/water flow to generate enough power to power the pump and arduino
@@MohammadShafinulHaque is it possible for me to just attach a capacitor to the turbine?
thank you
Thanks!
