Which direction do the loads and reactions go in a Ferris wheel?

Click For Summary
SUMMARY

The discussion focuses on the load and reaction dynamics in a Ferris wheel structure, particularly one utilizing pretensioned cables as spokes. It is established that the outer ring of the Ferris wheel hangs from the bottom spokes, which transfer tension loads from the hub to the bottom arc of the rim. The load at the hub and main axle is effectively transmitted down to the ground through two A-shaped frames. This analysis is crucial for understanding the structural integrity and mechanical behavior of Ferris wheel designs.

PREREQUISITES
  • Understanding of structural engineering principles
  • Knowledge of load transfer mechanisms in mechanical systems
  • Familiarity with tension and compression forces
  • Basic concepts of Ferris wheel design and mechanics
NEXT STEPS
  • Research the mechanics of tension in cable structures
  • Study the load distribution in circular structures
  • Explore the design principles of A-shaped frames in engineering
  • Learn about the dynamics of rotating systems in structural analysis
USEFUL FOR

Structural engineers, construction consultants, and students interested in mechanical design and load analysis of Ferris wheels and similar structures.

Considering a ferris wheel with the spokes being pretensioned cables. Which directions do the loads vs reactions go?

Can you produce for us a drawing? And then identify points where you think there is a load/reaction pair?

Welcome to PF. Is this question for schoolwork?

No. I am in construction consultancy but just interested

Welcome!
If the ferry wheel is like in a bicycle wheel, the outer ring is hanging from the bottom spokes, which transfer tension loads between the hub and the bottom arc of the rim in a sequence, as they are relocated by rotation respect to the vertical.
The load at the hub and main axle is transferred down onto the ground by two A-shaped frames.
