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

Place te gears closure

Thank you

Thank you sir

I want video without slow motion.

Great Explanation!

Thank you alot sir, finally I can understand this thing

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

I'm a civil engineering student and this whole playlist is extremely helpful. Thank you for publishing this

please sir i want to know prosesure how to calculate discharge ?and how to calculate steps of hf ?

hi can ı ask you question?

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!

SUBSCRIBE button was covering your display in the end.

Cool!

Wind.

Sped up AND not a delta robot... LOL. Nice job getting those clickies 👍

nice explanation about particle

How do i download multisim

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

It's not delta-robot. It's classic delta

can i pleas have a file

you are a brave man allah bless 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...

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

I remember we did these works, in a literal factory using approx 300 kilo engines.

THANK YOUUUYY😊

Why ?

what is the density of the quadrant?

Sir can I know why you add +2 after integrating, instead of t^2-1

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

Cool Also 🗿🤔💪🤬🥛🤓🍷☠️👌😡🥵🎅💀😭🎆🧒😏🇸🇦👏🤦‍♂️👴👨🏼‍🦳😌👋✌️🖕😩👇

This is great. Do you mind sharing how you were able to monitor how much votlage and current is produced by the generator? What sebsoe did you use?

Can you post the code and circuit diagram please 🙏

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.

thank you

Thanks!

What TPI blade used?
