Mary Said: I can recall my early days on pushbikes or motorbikes, when I'd have the occasional unexpected lurch because I got the tilt wrong and had to...
Here's a puzzler... push a 4-wheeled cart (shopping cart is fine) forward along the floor such that the 2 front wheels are fixed and the two rear wheels are...

snip I suppose I'm trying to imagine how reliable an auto-tilt ... One thing to consider is frequency vs severity of occurance. Stability of a car is more than...
Good catch Arthur, I think you got the trolley cart right on the money, I didn't think about the "directional stability" of the wheels. Regarding the hammer...
I was thinking about Phillip's Ball-Spline suspension idea today and stumbled on a possible derivative that should make it less expensive to build, less...

Hi Jonny, I'm not certain if there's a one piece hydraulic element that allows differentially adjustable flow controll in opposite directions, but you can...

snip ... The damping is an energy dissipating device, so needs to dissipate lots of heat. A simple hydraulic flow restrictor is not likely to do this well...
... Air has the problem of compressibility. As a damper, anyone who has used pneumatic machine components will be well aware of the limitations of air dampers....
... My experience with non rotating pistons (oval piston, square piston, square rod and hexagonal rod) in pneumatic applications has been that the rotational...
I'm not talking about manufacturing the non-rotating cylinder, they already exist off the shelf, I'm just not sure how they accomplish it. Perhaps it's...
... You could look at telescopic motorbike (or MTB) forks, as I mentioned before, as these do pretty much what you are talking about. I still feel separating...

Just thought I'd stumbled on a way to do it simply, cheaply, and light-weight with a single cylinder right off the shelf. I admit that it's probably got more...

Yes, the vehicle can balance itself, but not if the rider rigidly locks the control to one set angle to make a turn (such as in a car). Thus, the driver's...

From FFlist it is suggested that a 3 wheeled STV has been built with the very front wheel FTC. This ties in very nicely with our discussion re stability and...
