Moment of inertia2 Inertia of cylinderThe moment of inertia of a cylinder maybe obtained from the graphs to the right.The above graph isapplied for aluminum(specific gravity: 2.7)and the lower for steel(specific gravity: 7.85).The double-dot-chain linesindicate the allowable inertiafor each actuator.(Example)Material: AluminumDiameter: 100mmLength: 7mmForm: cylinderAs the diameter is 100mm,the radius is 50mm.Therefore, the above graphwould indicate that the inertia is:Approx. 1.9X10 -4 kg•m 2(Exact value: 0.000186 kg•m 2 )<strong>Harmonic</strong> <strong>Drive</strong> <strong>LLC</strong> 800-921-3332 46
