PROBLEM 10.69
Two identical uniform rods, each of weight
W
and length
L
, are attached
to pulleys that are connected by a belt as shown. Assuming that no
slipping occurs between the belt and the pulleys, determine the positions
of equilibrium of the system and state in each case whether the
equilibrium is stable, unstable, or neutral.
SOLUTION
Let each rod be of length
L
and weight
W
. Then the potential energy
V
is
