Two heavy rotating masses are connected by shafts of lengths l₁, l₂ and l₃ and the corresponding diameters are d₁, d₂ and d₃. This system is reduced to a torsionally equivalent system having uniform diameter d = d₁ of the shaft. The equivalent length of the shaft is

l = l₁ + l₂.(d₁/d₂)⁴ + l₃.(d₁/d₃)⁴

l₁ + l₂ + l₃

l = l₁ + l₂.(d₁/d₂)³ + l₂.(d₁/d₃)³

(l₁ + l₂ + l₃)/3

l = l₁ + l₂.(d₁/d₂)⁴ + l₃.(d₁/d₃)⁴

l₁ + l₂ + l₃

l = l₁ + l₂.(d₁/d₂)³ + l₂.(d₁/d₃)³

(l₁ + l₂ + l₃)/3
