A motor turns gear R in a paper-feed mechanism. Gear R is larger than the interlocking gear S. Gear R is the driving gear.
A student makes two predictions.
Prediction 1: Gear S will complete fewer rotations in one minute than gear R.
Prediction 2: The moment at the axle of gear S will be smaller than the moment at the axle of gear R.
Which predictions are correct?
Prediction 1 only is correct
Both prediction 1 and prediction 2 are correct
Prediction 2 only is correct
Neither prediction 1 nor prediction 2 is correct
