The bars are in equilibrium, each 5 m long,
and each weighing 82 N. The string pulling
down on the two bars is attached 0.6 m from
the fulcrum on the leftmost bar and 0.5 m
from the left end of the rightmost bar. The
spring (of constant 32 N/cm) is attached at
an angle 29

at the left end of the upper bar.
