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 '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Free fall of person in a sled to direct horizontal motion by atmospheric resistance'

Let there be a person in a not yet optimally designed sled at h meters in height. Let this sled free fall but user can steer by tilting their body weight in the sled or by optimal sled shape design point it in some horizontal direction where it is wanted to go - in any horizontal direction but once picked fixed. How to calculate horizontal distance d achievable as function of height h. Thus what is f(h) = d. Put another way, imagine a helicopter rises to a height h, but then shuts off all...
