r1= radius of drive pulley (mm) η = efficiency of belt drive system Notice that the efficiency (η) of the belt drive system is included in the torque equation. This efficiency accounts for losses such as friction between the belt and pulleys. Also note that we’ve assumed the drive and...
A 0.075 kg ball in a kinetic sculpture is raised 1.32 m above the ground by a motorized vertical conveyor belt. A constant frictional force of 0.350 N acts in the direction opposite the conveyor belt' An m kg object is initially at rest in...
