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

AI Thread Summary
In a Ferris wheel with pretensioned cable spokes, the loads primarily act downward due to gravity, while the reactions from the structure counteract these loads. The outer ring of the Ferris wheel hangs from the bottom spokes, which transfer tension loads from the hub to the rim as the wheel rotates. The load at the hub and main axle is directed downward and is transferred to the ground through A-shaped frames. Understanding these load and reaction dynamics is crucial for structural integrity in construction consultancy. This analysis highlights the importance of tension and support in the design of rotating structures like Ferris wheels.

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.

Thread 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'

Here are two fragments from Banach's monograph in Mechanics I have never seen the term <<velocity of transport>> in English texts. Actually I have never seen this term being named somehow in English. This term has a name in Russian books. I looked through the original Banach's text in Polish and there is a Polish name for this term. It is a little bit surprising that the Polish name differs from the Russian one and also differs from this English translation. My question is: Is there...

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
