2. If the ultimate tensile stress of Charmin Ultra Strong is 0.4psi, determine the maximum acceleration with which you can begin to extract paper from a fresh roll (assume bin outer diameter and 1.5in inner with weight 0.125lbf). Also consider that friction causes a moment (equal in static and kinetic) which resists the unwinding at 0.1 in lbf and that the pulling force is distributed against the entire cross-sectional area of the paper (4in x Xsin). Hint : 165 = r slug: Jl, 10 =3m(r+r2), 12in=14.0=-
