How to Solve a Problem with Multiple Pulleys - Finding the Tension

[@Olivia-jq3xh]

Thank you so much! I couldn't understand a similar question on my physics homework, even after attempting to solve it multiple times. Your explanation helped me understand where I was going wrong.

your explanations are very well and also the exercises are a lot of fun. Keep up the good work 👍

Outstanding explanation. Thank you so much.

I have a question... If i created a pulley system from top to bottom of the empire state building and you had a trigger like as if in a pistol still able to complete a pull as easily as if you fired the gun what is the heaviest weight you would be able to pick up?

hello, a query, a disk performs a uniformly varied circular motion, starting from rest, and with angular acceleration y. for the movement of a point on the disk that is at a distance R from the axis of rotation. I would like to know why this statement is false: the acceleration vector is always perpendicular to the velocity vector.

The acceleration will be directed toward the center of the circle if the speed is constant. In this case the speed is increasing, therefore there will be a component of the accent directed towards the center of the circle and a component tangent to the circle.

What if we wanted to count the mass of the pulleys? How would we proceed? Would we have to add to the equation the moment of inertia of the pulleys and their angular velocity/angular acceleration? Can you explain please? Thank you.

why is T1 T2 and T3 equal?

Tension will be the same everywhere on the main string.
