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)/3

l = l₁ + l₂.(d₁/d₂)³ + l₂.(d₁/d₃)³

l₁ + l₂ + l₃

l = l₁ + l₂.(d₁/d₂)⁴ + l₃.(d₁/d₃)⁴

(l₁ + l₂ + l₃)/3

l = l₁ + l₂.(d₁/d₂)³ + l₂.(d₁/d₃)³

l₁ + l₂ + l₃

The Kutzbach criterion for determining the number of degrees of freedom (n) is (where l = number of links, j = number of joints and h = number of higher pairs)

n = 2(l - 1) - 2j - h

n = 2(l - 1) - 3j - h

n = 3(l - 1) - 2j - h

n = 3(l - 1) - 3j - h

n = 2(l - 1) - 2j - h

n = 2(l - 1) - 3j - h

n = 3(l - 1) - 2j - h

n = 3(l - 1) - 3j - h
