Theory of Machine 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 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 l = l₁ + l₂.(d₁/d₂)⁴ + l₃.(d₁/d₃)⁴ (l₁ + l₂ + l₃)/3 l = l₁ + l₂.(d₁/d₂)³ + l₂.(d₁/d₃)³ ANSWER DOWNLOAD EXAMIANS APP
