Rotary Table
In a system with a rotary table, the following must be considered:
 The weight or mass and size of the table
 Any parts or load the table is carrying
 The position of the load on the table, the distance from the center of the table will af-
fect the inertia
 How the table is being driven and supported also affects the inertia
Belt Drive
In a system with a belt drive, the following must be considered:
 The weight or mass and size of the driving pulley
 The tension and/or friction of the belt
 The weight or mass and size of the driven pulley
 Any load the system may be moving or carrying
