Two shafts 'A' and 'B' transmit the same power. The speed of shaft 'A' is 250 r.p.m. and that of shaft 'B' is 300 r.p.m. The shaft 'B' has the greater diameter.

Speed is inversely proportional to the Dia of shaft.

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

P=(2*π*N*T/60).
So for same power, NT=Constant.
Therefore for less rpm more torque is transferred, so greater the torque greater is the diameter.

Interms of speed, we use less diameter shafts.

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

If the RPM is increasing then diameter value should be small but not big. And vice-versa if the RPM value is decreasing then it should have bigger diameter.

As per the chemistry rule, we all know that mobility of any particle (i.e. speed is inversely proportional to its size) Here B's mobility is more so it must have a less diameter.

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

Diameter of a shaft in any power transmission is directly proportional to shaft speed.

v = π * D * N/60.
From this v is proportional to diameter and N both. So, I think the statement is true.
