AI Thread Summary
The discussion focuses on the principles of Newton's equations and the effects of centripetal force on water in a rotating ferris wheel. It emphasizes that constant velocity motion is indistinguishable from being stationary, and only changes in velocity can be measured. The centripetal force acts on the water, causing it to tilt away from the center of rotation, resulting in a higher water level at the sides of the container. This clarification helps the junior participant understand the dynamics involved in their project. Overall, the conversation effectively addresses misconceptions about motion and forces in a rotating system.

Alrighty, thanks FZ+.

Er... I think you misunderstand Newton's equations here. There is a principle of relativity which states that travel at constant velocity is indistinguishible from being stationary. Thus, you can only measure change in velocity, not actual movement. Circular motion is different...


Secondly, I think that on the ferris wheel, centripetel force would pull the water towards the center of the circle. Wouldn't this express itself as a tilting of the water towards the center though?
No. There is an acceleration on the water towards the center, yes, but that is applied by the sides of the container. The water, by Newton's first law, will move at a tangential velocity until it is accelerated. So you should see an increase in water level away from your centre of rotation, where contact forces are acting to stop your water overflowing...
 
So the water would "tilt" away from the center? I know I'm new at this, so I appreciate your pointers.
 
Yes, it would tilt away, giving a higher water level at the sides and a lower level in the centre.
 
Excellent, this cleared up quite a bit. Thanks very much.

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Calculation of Tensile Forces in Piston-Type Water-Lifting Devices at Elevated Locations'

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
