I was looking at a wikipedia page of the minimum turn radii of various systems — both the MBTA Green Line and the Newark Subway have a minimum curve radius of 33 feet. I know both of these systems operated PCC streetcars extensively over many decades, however, the numbers on what the minimum curve radius a PCC can navigate seem to be well above 33 feet. Did curve radius vary between the different iterations of the PCC that were built? I know they could vary fairly extensively in length.
I am in general physics and we are going over centripetal motion. For a centripetal motion problem where a mass is going around a banked curve is it possible to derive an equation to find minimum radius of the curve before the mass begins to slide up ? I feel like the radius is independent and the other variables such as velocity are dependent on radius, someone else in my group disagrees. Thanks for the help.
I am looking to build a layout in my apartment with some HO equipment I had as a kid. What is the minimum radius of track that I could use as I start designing and building the layout?

I purchased an observation / passenger car for my small N scale track. Most of the rolling stock on my N scale have axel mounted couplers but the passenger cars that I ordered have body mounted couplers. I ordered them from train world, the Micro Trains #14300150 28-1 Heavyweight Parlor Car, Canadian National "Gatineau" and the Micro Trains #14300320 28-1 Heavyweight Parlor Car, Northern Pacific #633 . Since they do have body mounted couplers and the track has to be built with 11 inch radius curves, they become detached from my other cars with axel mounted couplers due to the angle of the axles vs. these long body cars. Do they make a conversion where I can attach axel mounted couplers to these new cars? TIA.
Trying to lay ground work and the curve radius is doing nothing. Need help trying to figure it out
Minimizing the radius seems reasonable as to cover the least arc length but what is the cause behind slowing down?
In this curve, the variable 'n' controls the shape of the curve, while 'h' and 'k' are being used to translate the curve horizontally and vertically. I'd like to change how the curve is translated however, with one variable 'L' changing the curve's X,Y position on the perimeter of a circle, and 'R' changing the radius of said circle. Some help with figuring out where to start in going about doing this is all I really need.
(Also side note, is anybody able show me what the 3d shape this curve creates assuming it's a cross section over value 'n'? I've always wanted to know.)
Some things would be excluded such as WFH and default to regular minimum wage.
Implementation details are up for debate. The core of the idea is that one should be able to afford housing in a reasonable distance from their job if they would work full time.
What is the minimum scan radius needed to find all the hacking and deadspace sites? I’m at 77.12 right now. Is that good enough?
Second time taking 2E, I’m at a 66.77 and cannot afford to get below a C- a second time :)
