39. The particles are treated “pointlike” in the sense that Eq. 1033 yields their rotational
inertia, and the rotational inertia for the rods is figured using Table 102(e) and the
parallelaxis theorem (Eq. 1036).
(a) With subscript 1 standing for the rod nearest the axis and 4 for the particle farthest
from it, we have
