## Homework Statement

- Weight - 200kg
- RPM - 5
- Diameter - 6m

## Homework Equations

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.
