How Levers, Pulleys and Gears Work

⚙️ This video explores different methods that can be use to amplify a force, and focuses on three types of machine - levers, pulleys and gears. The amplification of a force is called mechanical advantage, and it is useful for a wide range of applications, like lifting heavy loads.

As a ME student that hasn't taken statics in a while, this was a great refresher!

[JesusMartinez-zuxl]

while most people are out on Friday night i'm here watching these videos. I finally understand mechanical advantage! Thank you!

[Danish_Raza]

I am a graduate mechanical engineering I have been preparing for PG entrance exam of Engineering. Believe me!! You will never find this level of animation I mean classical mechanics with such an perfect examples and articulate animation!!!
May Allah bless you and except your efforts!! Love and Respect from India

I am so eternally grateful for this channel. I will become a patron once I graduate and stop being poor.

[sipanaskar]

Please make more videos, I love them watch all of them! Great work as always

[josephlai]

Thank you for sharing. The animation is so wonderfully done. It made understanding the subject so much easier. And the logical progression of explaining from lever to pulley to gears is extremely clever and well thought out. This must have required a lot of imagination and fore thought.

This is now the best channel that I have watched in YouTube in terms of explaining engineering concepts and clear animations. I've almost watched all the videos in this channel. Thanks and keep it coming.

A gear can also be seen as a wheel of levers where the moment is at the center of the gear and each tooth is it’s own lever. Great video! ❤

[hagenherrmann]

These are next-level animations paired with top notch explanations. Thank you for this most excellent refresher and keep up the great work!

[ziaddagher]

You are doing GREAT work these videos have immersuable value for everyone watching them, it is a joy to learn engineering with this kind of quality content to support the classroom, on behalf of every aspiring engineer Thank You

[blackkats]

This is by far the most concise explanation of these concepts I have come across. Excellent work, thank you for the information!

[martyjoseph]

One of the best explanations I've ever seen, covering many questions at once

[justadude]

I was confused by pulleys and how they work and your video made everything clear to me!

[shubhamraj]

All your videos are gold. It not only bring concept and knowledge, but also develops more interest which is most important thing.

[francoisl]

It's been so many year's since I've graduated. Your videos are so helpful to refresh high level conceptual concepts. Thanks

[mrmnty]

This video would've been so useful back in my hs days. The information was delivered in a very easy to understand and digest manner. Great work

[josammarenye]

I love how gears amp up speed in a given period of time. They're the reason I fell in love with cycling 😄
It's a great video

[golmaal]

As a mechanical engineering student I really love your videos. I appreciate how you include every minute details in your video. They way you explain the concepts is phenomenal. Only thing that bothers me is the frequency of your videos which come in Months.

[dtcarrick]

As a Physics teacher I wish I could buy you guys a pint - These animations are perfect!

I wish videos like this existed when I was in college. We had YouTube, but it was the early days of it and mostly just people doing stupid things. It also took an hour to load a 5 minute video! I'm enjoying relearning the basics recently, so much of this stuff quickly gets forgotten after the exams if it's not regularly used!
