Question
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 = 9.4 kg, m₂ = 6.9 kg, and m3 = 7.7 kg. The magnitude of the force is F = 495 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
5.39 s?
