PROBLEM 10.79
A slender rod
AB
, of mass
m
, is attached to two blocks
A
and
B
that can
move freely in the guides shown. The constant of the spring is
k
, and the
spring is unstretched when
AB
is horizontal. Neglecting the weight of the
blocks, derive an equation in
,
θ
m
,
l
, and
k
that must be satisfied when
the rod is in equilibrium.
