Solve a,b,c and for c when the two dampers are connected to rigid bar (not parallel or series)

Find a single equivalent damping constant for the following cases:
When two dampers are parallel.
When two dampers are in series.
At A, when two dampers are connected to a rigid bar as shown below.
Pivot O
C1
777
H
x₁ c₂
fiz
777
A
(i) Using the moment equilibrium about O.
(ii) Using dissipating energy equivalence. Assume small angle displacement and the energy dissipated
by a damper is cx² where x is displacement. Did you get the same results from (i) and (ii)?
