Question A motor is spinning with angular w = 5000 rpm as shown in Figure 1. a) Using manual calculation, determine the precession velocity 12 of the mechanism when a mass, m=0.15 kg is attached at point with radius, r=0.15 m (mass moment of inertia /=0.0035 kg.ms) b) The period of precision, Tis taken when the rod horizontal is released from the angle, 0 = 0 to 45 (view from top). Using MATLAB script, plot graph M vs (12xw) if radius, r is set from 0.12 m and increasing in increments of 0.01 m up to 0.30 m maximum radius. The estimation precision period can be calculated using following equation: T=r/1.3 c) Discuss the result obtained 1 mass, m Figure 1
