Mechanical Engineering: Ch 11: Friction (20 of 47) The Wedge: Basic Concept

Visit ilectureonline.com for more math and science lectures!
In this video I will explain the basic concept of a wedge of how it's used and how forces act on a wedge.
Next video in this series can be seen at:
• Mechanical Engineering...

[@lamada1997]

you are absolutely the best lecturer i have ever seen
every time i search for something i find it at you channel
thank you Michel van Biezen

[@razzmatazz6233]

amazing clear explanation. totally learned much more here than my current engineering mechanics class. thank u very much

[@MichelvanBiezen]

You are welcome. Glad you found our videos. 🙂

[@svenssonpatrik]

Hi, would it be possible to calculate the needed force to pull out the wedge again. Imagine that there is a roof above A and that we use the wedge to clamp A against the roof. Then with the friction it would need some extra force to release the wedge again. A real life troubble I am dealing with right now.. Thanks for a great explanation video

[@vans6084]

bro thank you so much! this was the video that made me FINALLY understand these stupid questions! thank you so very much!!

[@SoumilSahu]

they're not stupid, but I agree. This dude is gifted

[@enockbambe1821]

GOD BLESS YOU AM HELPED

[@phamquoctan]

thanks for your videos . Michel van Biezen . it is very useful for me.
please keep doing your work
. From Alex , Charles Darwin University.

[@MichelvanBiezen]

Glad we can help. Darwin is one of those places in the world that is fairly isolated. It must be beautiful there.

sir = no body on you tube can explain concepts like you = i do not under stand truss - i have seen many lectures = pray explain truss -- thank u sir

[@MichelvanBiezen]

Did you see this playlist on the channel? MECHANICAL ENGINEERING 8 TRUSSES AND BRIDGES

[@kavin1716]

I am learning it at class 11:)

[@wordsareuneccesary]

If I and when I make money thanks to you I will fund whatever project you want.

[@eatbareph]

Pls upload more CE related lectures ☺

[@blessing_olaniyan]

sir,what if d block is inclined

[@svrt5832]

Is the direction of fka correct? It should oppose the sliding right? why is it placed on the same side?

[@MichelvanBiezen]

The direction of the friction force on block "a" caused by the wedge being pushed to the right is to the right as well.

[@RaagDawg11]

super helpful! thank you! ❤

[@MichelvanBiezen]

Glad you found our videos. 🙂

[@ricjadelacruz2808]

Sir what if the weight of the wedge is not negligible? What is the FBD of both? Thank you!

[@oximeter_x20a]

Why is the friction force at block.a is the same.direction as the force.F?

[@MichelvanBiezen]

The direction of the friction force from block A onto block B is to the right. The direction of the friction force from block B onto block A is to the left. (Newton's third law)

[@oximeter_x20a]

@@MichelvanBiezen Ohhh now I get it, thank you sooo much sir🤗

[@qantas-pt6yv]

Treat block A as a separate system. Now see the forces on this A block.
Since you move the wedge towards right but relatively the block A moves towards left, that is why friction is towards right.

[@wordsareuneccesary]

Where is the wedges own weight being factored in?

[@MichelvanBiezen]

The mass of the wedge is insignificant compared to the mass of the block.

[@wordsareuneccesary]

Thanks. Still going through these now :)

[@MiMi-wg4jk]

u will save me from failing my course hurhur

[@MariaTeresa-yk7yo]

Whats the book's name where I can find those exercises? Pleaseeee :( I need it

[@MichelvanBiezen]

Any mechanical engineering book will cover this topic.

[@MariaTeresa-yk7yo]

Ya. But I meant, where you found this exercise specifically. Isnt Beer Johnston right?

[@MariaTeresa-yk7yo]

I need the mathematical calculations (solution) I hope you can help me
