- Homework Statement
- No friction, massless string, massless pulley and wedge M is not fixed, pulley is attached to M.
Apply Newton's 2nd law on (Mass M + pulley) in Horizontal and Vertical directions.
My question: When I was watching this on YouTube, the teacher summed the forces as usual(I've added a picture). But there is a force of tension acting on the top right of wedge, so wouldn't that create a torque... Or something? What force counters that torque? And why can we just sum the forces as usual rather than thinking about the torques?
Also, I've added an image(blue ink) of how the forces kinda look like on the (Mass M + pulley) system
