1. Still can't wrap my mind around it :/

2. The main problem: https://arxiv.org/abs/physics/0510204

   Full course of this session: https://ocw.mit.edu/courses/physics/8-01sc-classical-mechanics-fall-2016/week-4-drag-forces-constraints-and-continuous-systems/week-4-introduction/

3. Loved this series of videos. It explains the real math behind pulley's that really allows you to visualise the forces at play and how the system works.

4. I can understand why MIT is best.

5. theres also a virtual work concept

6. I have one doubt.If change in y1=-2*change in y2 in a given time interval ,then how can we conclude that the velocities and acceleration of 1 is twice that of 2.I can sense that however if you can derive it mathematically it would be great.

7. Sir which type of your board
