Question
One end of a rod of length
L and density p is fixed by a
frictionless pivot at a depth
L
d under water. Determine
the equilibrium positions of
d
the rod in terms of its an-
gle a measured from the
vertical, and the investi-
gate whether the equilib-
rium positions are stable or
unstable, given that
(a) p= 500 kg/m³3;
(The density of water is pw =
(b) p = 853 kg/m³.
1000 kg/m³.)
