Technician A says belt tension on a variable-diameter pulley (VDP) system is maintained by a large spring on the output shaft pulley. Technician B says the tension spring on a variable-diameter pulley (VDP) system causes the sheaves of the output pulley to be close together, creating a larger diameter pulley. Who is correct?
