Not really HW, just revision.

A shaft rotating at 3000 revolutions per minute is transmitting power of 10000 watts. find the size of the driving couple.

2. Relevant equations

Total wrk done by couple = 2.F.r.θ

Work = Torque . θ ( angle of rotation )

Power = work done / time

3. The attempt at a solution

60 seconds = 3000 revolutions

1 second = ?

Ans came to 50

Using ω = 2∏f resulted in ω = 100∏

Power = (Torque . θ)/t where θ/t = ω

Subject of the formula gave me 9.54 as an answer. When it should be 32Nm

What have I done wrong?
