Question - An engineer is designing a conveyor system for loading hay bales into a wagon (Fig. 11.57). Each
bale is 0.25 m wide, 0.50 m high, and 0.80 m long (the dimension perpendicular to the plane of the
figure), with mass 30.0 kg. The center of gravity of each bale is at its geometrical center. The
coefficient of static friction between a bale and the conveyor belt is 0.60, and the belt moves with
constant speed.
(a) The angle f3 of the conveyor is slowly increased. At some critical angle a bale will tip (if it doesn't
slip first), and at some different critical angle it will slip (if it doesn't tip first). Find the two critical angles
and determine which happens at the smaller angle.
(b) Would the outcome of part (a) be different if the ...Read More
