4.30 A cylindrical roller with mass m, radius r and moment of inertia I with respect to the axis of rotation, is pushed forward by the force P forming the angle B with the horizontal plane. Determine the angular acceleration of the cylinder if the friction number u is large enough for the cylinder to roll without slipping. The rod between the handle and the cylinder is light. What friction number umin is required? You have to draw the free body diagram and kinematic diagram of the figure. The answaer of the question is I * Pcosß (I + mr²)(mg + Psinß) 4.30 A cylindrical roller with mass m, radius r and moment of inertia I with respect to the axis of rotation, is pushed forward by the force P forming the angle B with the horizontal plane.
