both technician A and Technician B are correct

Explanation:

Technician A says balance shafts are used to counteract vibration created in the engine. Technician B says proper balancing of the engine is important for smooth operation. Which technician is correct

In piston engine engineering, a balance shaft is an eccentric weighted shaft that  counteracts vibrations in engine designs that are not inherently balanced. They were first invented and patented by British engineer Frederick W. Lanchester in 1904. ... .The balance shafts have eccentric weights and rotate in opposite direction to each other, which generates a net vertical force. Unavailability of the balance shaft can cause excessive vibration to the engine thereby damaging the oil pump and resulting to engine failure.
