- Homework Statement
- A cardboard strip, folded in U shape, is placed on an inclined plane, as shown in the figure. Length of the two parallel sections is n = 1.5 times of the length of the middle section,that is a square. At what minimun angle of inclination theta will the cardboard topple? Friction is sufficient to prevent sliding
- Relevant Equations
- Torque
It is crystal clear that we need torque equation to solve this. But, in order to do so, I need to know where the normal force is located. As far as I'm concerned, normal force is not distributed equally. If this is true, then I suppose this problem is unsolvable? (Though the book says thay it is possible to solve them)
