onsider the rolling cone in Figure 9.20. Pivot O is fixed. It is given that friction is sufficient to prevent slipping. The cone will tip if its rolling speed exceeds a critical value. Find this critical speed in terms of v and L, for when R/L = 0.2. Hint: Use the shape frame and model the normal force acting on the cone as a single force acting at a distance d from O and relate the angular velocity to d.
