About the maintenance forces the values are: - Pushing action: ℎ = 53 N; - Pulling action: = 52 N. 3. Multi-body model The CAD model of the investigated cart has been realized, consisting in the chassis, the base and the four wheels, two fixed and two floating, composed each one by two steel disks (Fig. 2).
