Just ... I admire all your work and the frequent uploads. But I am starting to get worried about your health. With all those videos, do you even sleep ? Rest a bit, we would not want you to make a burn out. You deserve to take some vacations.

My teacher did a horrible job at explaining this in over half an hour and i ended up not understanding one bit. Thanks for being able to do it better 6x faster

bro u explained this WAYY better than my teacher, i am able to understand this know ur a w man

I have been so confused about this concept for some reason, but this is the first video I saw where it finally clicked. Very well explained, thank you. You presented a simple topic as it should be presented...simply.

This is very informative, and i definitely understand it better now. I've looked through most of your video lists and haven't found one on what I'm really struggling with though. If you haven't already would you make a video for class two levers in the future. Honestly i did okay in physical science in high school but that was 14 years ago. I'm taking a course for mechanics (literally for cars) right now. Pascal's Law, Ohms Law, calculating leverage, Newton's Laws, compression ratios and conversions, inertia, traction, gravitational force, cintrifical force.... OMG seriously?! Your channel is my life saver.

You are genius person around the world keep it up

I wanted to know how a lever works. I spent hours researching and I couldn't find any good images or videos. I was reading articles about it but still couldn't understand it. Then I came across your video and it explained to me everything! Such a relief! Great work! Thank you!

this is a very cool, brilliant, awesome, good, great, quality, useful, helpful video. Thank you for sharing your time and knowledge on this very cool but brilliant and awesome simple machine.

I needed this last year

Simply spectacular really appreciate your work keep on

I like very much your voice and pitch! Gives me peace to learn and understand. You are a Blessing. 🙏🏻👏🏻🌺

Thanks for the excellent video which lets me understand the principles - well at least some. I do have a question. If the lever is balanced horizontally on the fulcrum, and a small amount of additional weight is applied to one side, what determines how quickly that side will fall to the bottom and what relative amount of weight is required to partially or fully unbalance it. An analogy would be a playground see-saw. Consider one person on each side of exactly the same weight. If you add a pound to one person the equilibrium shift but perhaps only a few degrees. If you add 10 lbs to one side it may be sufficient to cause the opposite site to coast slowly to the ground. Addition of 100 lbs will cause the side to plummet to the ground like a heavy stone. Is there some way to calculate it. In my case I am trying to design a simple lever that will maximize the weight required to allow the extra load to cause the lever to drop around 20 degrees and not fully collapse the side. I hope that makes sense. Thanks and best regards, Murray

can you make a short vid about how mechanical advantage is used in an engine's gearboxes and different gears? would look for another source but I really like your vids an the way you explain things more. P.s thanks for helping me get through calculus btw

This guy helped me pass my math exam

Thank you

If you make any Mechanical Engineering videos, I will donate for sure.

Nice

Plz upload more mechanic videos !

What is the principle of lever

shoudnt be like Fout = Fin 100n * 4ft - Fin100n *1ft ? . So the output force decrease if " 1ft" ( output ) is longer , so if on both sides of rotating point we got 4ft then Fin=Fout ?!

I'm sure this isn't going to be answered in time but if a question asks about the mechanical advantage of a lever itd just be ma=fin/fout?

my guy do be having a minecraft boss health bar under "The Lever"

Why are there so many viewers who don't like the video??w

:D
