Considering a ferris wheel with the spokes being pretensioned cables. Which directions do the loads vs reactions go?
Which direction do the loads and reactions go in a Ferris wheel?
Click For Summary
Discussion Overview
The discussion revolves around the direction of loads and reactions in a Ferris wheel, specifically considering the structure as having pretensioned cables for spokes. The scope includes conceptual understanding and technical reasoning related to structural mechanics.
Discussion Character
- Technical explanation
- Conceptual clarification
Main Points Raised
- One participant asks about the directions of loads and reactions in a Ferris wheel with pretensioned cables.
- Another participant requests a drawing to identify load/reaction pairs, indicating a need for visual representation in understanding the mechanics.
- A participant inquires if the question is related to schoolwork, suggesting a context of educational or professional inquiry.
- A later reply clarifies that the inquiry is not for schoolwork but stems from an interest in construction consultancy.
- Another participant describes the mechanics of the Ferris wheel, comparing it to a bicycle wheel, and explains how the outer ring is supported by the spokes, transferring tension loads to the hub and down to the ground through A-shaped frames.
Areas of Agreement / Disagreement
The discussion does not appear to reach a consensus on the specific directions of loads and reactions, as participants are exploring the topic and providing different perspectives without resolving the question.
Contextual Notes
Participants have not provided specific definitions for loads and reactions, and there may be assumptions regarding the structural configuration that are not explicitly stated.

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

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.
