Problem D6:
A thin rod has a non-uniform linear mass density. If the left end is at
x=0, the linear mass density is λ = c xn1 where
c is a constant. The length of the rod is n2 l0.
Find the ratio of the rotational inertial I about the left end to
l02. If I/(ml02) = n3,
what is n3? Note: n1, n2, and n3
are unitless.
