I saw someone make a quick cheat for it. Write F L E on a sheet of paper, then under it, align the numbers 1 2 3. The way to read it is 1st class has the letter F in the middle for fulcrum. The 2nd class has the Lever in the middle. The 3rd class has the effort in the middle. FLE=123 tells you which class and what’s in the middle!
A hammer can be used as all three depending on application. 1st class when pulling a nail, 2nd class when rip-clawing a board, and 3rd when driving a nail.
Yes, he must be a physics professor like me. We are always wrong, but that's what's so right about us. That's a joke by the way for those over-sensitive people out there.
Thanks Sir i am in class 9 , you explained it to me on an Extreame Basic Fundamental level about The worrking and differences between classes of levers , i am preparing for JEE Advanced , where your bacis and Concepts should be Extreamly and crystal clear . Thanks a lot as it helps me in Solving Extreamly Advanced level questions . Thanks
Well that's to the failure point. How ever as a mechanic I can say with certainty depending on the door jamb that the striker will move if the person is heavy enough. Sometimes they need a bit of tweaking and they make a tool that grabs the striker and will allow it to move. I will say I don't have this step to examine and try out so that leaves wiggle room for error but unless it's loading parallel to it's mount it will flex the steel the striker is mounted in even tho it's generally double and sometimes triple layered but that's only around the striker. This step looks like it touches the jamb bellow the striker and more than likely any layering inside and the weight is supported out at the end of a striker. That's basically a 3rd class lever, given proper weight it will bend the jamb. Strikers are tough as hell but not the door jamb which any firefighter using jaws of life will tell you is where to cut not the striker.
When would it actually be preferable to use a second class lever rather than one of the other two classes? I can see why a 3rd class lever would be better to use for a task - a good example being tongs, where you want to control a fine movement which might be difficult with your over powerful and clumsy hand.
Sorry for any confusion. I had the arrows in the direction that the force is acting on the load. As a result I created a new video, and added a nice mnemonic device to help memorize the different types. th-cam.com/video/fzljPiPy9nw/w-d-xo.html
This video is wrong - All the arrows for "Load" are backwards! The arrows for "Load" should indicate the direction of resistance, which the "Effort" is counteracting.

The last picture says 2nd class but a hammer is a 3rd class lever. Other wise great video!!! Very easy to understand
depends on if you swing it or use it to pull a nail if you use it to pull a nail its a 2nd class if u use it to hit a nail its 3rd class.
but you are right he was swinging it so it was 3rd class

Thanks for the feedback. A hammer is a 3rd class lever, I just labeled it wrong and didn't notice this.

Almost screwed me up on my test saying the hammer is a second class leveler!
@Aarav Iyer They said leverler not leverer- also why u replying to a comment that was 4 months only. See mine was only 2 months.

No hammer is a First-class lever
Great video easy to follow. Need to change letter head of hammer to Class 3. Showing as class 2. Thanks,
Why is the load pointed up? Wouldn’t it be weighing down so the arrows pointed down?
Thank you very much bro I am not going to be confused now on first, second and third class leaver.Again thank you bro❤️❤️👍👍.

Wow, it's helpful.
1nd 2rd 3th 4rd 5st
Very informative
Thank you very much i hope it will surely helps in my exams
Best explanation
Good Explanation loved it 🙂 👍👌
No wonder our calves seem to be stronger than our quads. Calf raises are 2nd class lever movements and squats are 3rd class lever movements.
Thank you very helpful
I love levers! they level the playing fields in life ;)
Thanks for this I’m too lazy to look at the textbook
Hi how do i answer this question 4. Write a statement comparing the advantages of Class 1, Class 2, and Class 3 levers.
Good
Thank you!
The arrows showing the force direction are surely incorrect? the load would oppose the effort surely?
thanks good information
❤❤❤❤🎉well done!
Thank you sir 😊
good short video
Thank you sir
OP- Overpowered
you have your 2nd and 3d class levers mixed up. In a second class level, the load arrow should be facing downward
Sorry for any confusion. I had the arrows in the direction that the force is acting on the load. As a result I created a new video, and added a nice mnemonic device to help memorize the different types.

stapler is an example for 3rd class leveler
Thank u 💕
Exuse me,I think you messed up ham,er which is third class for second class.if you could see this comment and reply I would be grateful. Thank you.
You put the direction of the load in the wrong way tho cause its supposed to oppose the effort
POV your teacher give this as a lesson 😂😂😂😂😂😂😂😂
A stapler is 3rd class lever
Please send me more
