I am pleased to join this forum to learn something from experienced guys and thanks in advance for helping me to understand physics.

I am trying to design a Ferris wheel with maximum SPEED and maximum PASSENGER capacity. I want to know formula to calculate MOTOR POWER IN KW to rotate that Ferris wheel. Here are general specs of the wheel.

Diameter: 106 Meter

Radius: 53

Wheel total weight: 1000 Ton

Exclude Wheel standing structure: 30%

Rotating Wheel weight: 700 ton (Everything including spindle, hub, bearing, spoke cables, rim, cabin, riders weight, etc)

Minutes Per Round: 10 (1 round completed in 10 minutes)

Round Per Minute: 0.10

Wheel Speed: .55 meter per second

For this calculation if only rim, spoke cables, cabin/rider weight is required then you can make rough estimate what might be the weight of spindle, hub, bearing, etc. which are creating force. You can make an assumption and then calculate on that assumption. I will fix formula in Excel as per given here and then adjust weight.

**I want to know**1. What is total torque generated by wheel (Newton Meters / Joules)

2. What power motor in HP or KW I needed to rotate this wheel

Once I get formula then I can set that formula in Excel and try to change speed to find good results.

Please help me.

Thanks
