- I have the solutions and questions below
- Relevant Equations
- Sum of moment = (Moment of inertia)*(angular velocity)
So for this question, when using point B as the centre of the moment, I get different sign for the mad term. If you take clockwise as positive than 100N force and the force at point G are causing a positive moment and gravity is causing an negative moment. But the solutions have different signs as my attempt I don’t understand why. Appreciate it if someone can explain this to me.
