g rll The 21-kg roll of paper has a radius of gyration ka = 90 mm about an axis passing through point A. It is pin supported at both ends by two brackets AB. The roll rests against a wall for which the coefficient of kinetic friction is s, = 0.3. Neglect the mass of paper that is removed. (Figure 1) Part A Determine the magnitude of the constant vertical force F that must be applied to the roll to pull off 1m of paper in t = 3s starting from rest.
