Web21 Sep 2024 · This issue is unique to having an odd number of pulleys in a loop. It was tricky to understand the issue. One way to think about it is considering the simplified model below: the Simscape solver requires that the forces sum to 0 at the nodes: i.e. for pulleys 0, 1, and 2, the model has F0A = -F1B, F0B= -F2A, and F2B= -F1A. Web8 Oct 2014 · In general, you need to take the vector sum of all torques - torque as a vector is perpendicular to both the force vector, and the arm. Or if you like, for a force $\vec{F}$ at distance $\vec{r}$ from the c.o.m., the torque vector $\vec{\Gamma}$ is (note: formula was edited. Originally sign was wrong.
