QUESTION 18 In the system shown bellow, the rack has mass M and the pinion has mass moment of inertia J The Indas of the gear is it Vet is the relation between v and 60 0, @ B T(t) X,V M /11 K QUEST For the system of previous question, what equilibrium equation can be obtain for the rotating pinion? Consider fg being the action reaction force between contacting teeth in gears. OT-Bw-J-f=0 g OT-Ba-f=J JA+BA=T S OT-Bw-J0=f R g
