Acceleration of a Three Block Atwood Machine | 3 Blocks 2 Pulleys, 2 Strings, no Friction

Показать описание
Three blocks are connected by light strings which pass over frictionless pulleys such that two of the blocks are hanging. The blocks are released from rest, calculate the acceleration of the system (all three blocks).

This variant of Atwoods Machine is unique in that the middle block does not accelerate due to gravity, instead it accelerates exclusively due to a difference in tensions between the two strings.

This problem commonly comes up in introductory physics courses including AP Physics 1, AP Physics C Mechanics and appears on exams such as A Levels and JEE.

This actually did prevent me from crying all over my physics textbook. Thank you

Simple and straight forward Sir, excellent.

I have the exact same pen, you very handsome disembodied voice and hand.

It's a nice pen...

My teacher is a dick and added friction, but we have the acceleration. And we need to find the weight of the block on the left. Any tips for this because I’m kind of lost

If we have tk find net force exerted by pully on clamp then how can we find it

do you have a video including friction

Im not sure what I would do with the friction coefficient.

Thanks! mine had including friction, but honestly its not really that big of a deal. Just an extra -mewmg in there

love how you said you would show with friction in middle block but you did not. waste of my time
