A motor turns clockwise and operates the shaft that adjusts a ventilation damper. The output shaft must turn anticlockwise and more slowly than the motor.
A designer attaches a large driving gear to the motor. This interlocks with a smaller driven gear attached to the output shaft.
Explain whether the proposed gear system meets both requirements. Your answer should include how the rotational effect is transmitted.
Suggest one change to the gear system so that the output shaft meets both requirements.
