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

l₁ + l₂ + l₃

l = l₁ + l₂.(d₁/d₂)³ + l₂.(d₁/d₃)³

l = l₁ + l₂.(d₁/d₂)⁴ + l₃.(d₁/d₃)⁴

(l₁ + l₂ + l₃)/3

l₁ + l₂ + l₃

l = l₁ + l₂.(d₁/d₂)³ + l₂.(d₁/d₃)³

Theory of Machine
The Grubler's criterion for determining the degrees of freedom (n) of a mechanism having plane motion is (where l = Number of links, and j = Number of binary joints)

n = 4(l - 1) - 3j

n = 2(l - 1) - 2j

n = (l -1) - j

n = 3(l - 1) - 2j

n = 4(l - 1) - 3j

n = 2(l - 1) - 2j

n = (l -1) - j

n = 3(l - 1) - 2j
