Using the values below, calculate Jeq, Beq, and Aeq. You will need to calculate the total load moment of inertia Jl = Jl;ext + P Jgear;i, which includes contributions from any external connections and the four gears attached to the motor shaft. The external connection is a disc mounted to the load shaft and the four gears are one 24-tooth gear, two 72-tooth gears, and one 120-tooth gear. The associated radii rd, r24, r72, and r120 and masses md, m24, m72, and m120 are also below. Treat each gear as a uniform disc with constant radius.
