The drawing shows two identical systems of objects; each
consists of the same three small balls connected by massless rods.
In both systems the axis is perpendicular to the page, but it is
located at a different place, as shown. The same force of
magnitude F is applied to the same ball in each
system (see the drawing). The masses of the balls
are m1 = 9.8 kg, m2 = 6.9 kg,
and m3 = 7.6 kg. The
magnitude of the force
is F = 433 N. (a) For
each of the two systems, determine the moment of inertia about the
given axis of rotation. (b)Calculate the
torque (magnitude and direction) acting on each
system. (c) Both systems start from
rest, and the direction of the force moves with the system and
always points along the 4.00-m rod. What is the angular velocity of
each system after 5.24 s?
