p=2piNT/60.
There for torque and speed are inversely proportional. So b diameter is lesser than a.

Angular speed is inversely proportional to Torque.
And Torque is directly proportional to radius.
And Torque is directly proportional to radius.

Speed of shaft and its diameter both are inversely depends on so, less diameter have more speed.

If diameter of shaft increases means speed will decreases, on other hand, Torque will increases.

Shaft rpm can not determine by diameter. It Can be determined by hollow shaft and solid shaft.

Here the term "Two shafts ' is used.
Not Two Pulleys, so that I think no relation.

If dia of shaft is small then it's rotation is more than the larger dia of shaft.

P=2 * 3.14 * N * T/60.
Where T=p * R/2.
i.e. 'p' is directly proportional to R.
Where T=p * R/2.
i.e. 'p' is directly proportional to R.

P = TW.
T = PI*DN/60.
D = 1/N.
Diameter is inversely proportional to Rpm.
T = PI*DN/60.
D = 1/N.
Diameter is inversely proportional to Rpm.
