- Weight - 200kg
- RPM - 5
- Diameter - 6m
Moment of Inertia I = (weight/9.8).r^2
Torque t = I * (angular velocity / t)
Power = Torque * speed
The Attempt at a Solution
First I calculate
Moment of Inertia Using
I=(weight/9.8) * r^2 = 183 kg. m^2
Then I calculate Torque using
t=I∗(angularvelocity / t) = 96 Nm
where angular velocity is in rad/s.
Here is where I'm stuck if I take t as 1sec I get a Torque of 96 Nm.
If take t as 5 sec the I get a Torque of 19 Nm But my load is rotating at constant rpm of 5 so what would be the correct torque.
Once I get the torque I will find Power by P=Torque∗speed.
