No I don’t remember that one. Let me try that. I got 13.372mph..

I’m somewhat familiar with them, although it’s been a bit since I practiced it. I’m assuming it’s higher than 9.8m/s? I can’t really remember.

Yes this is exactly right and what I’m trying to figure out.

Don’t really understand your stiff question. When the platform is at its starting position, the hydraulic is not exerting any force on the platform so “zero stiff” I guess? Secondly, as far as speed, that’s part of my question. Obviously if you accelerate slowly the platform won’t be thrown at...

I’ll put a method to it. Say the platform in sitting on a solid object at rest but underneath the platform is hydraulic rams. The stroke of the ram is only 6” so all of the upward force will have to be exerted on the object in the time it takes the ram to move 6” and within that 6” distance. How...

It was a discussion that I saw recently but I changed the numbers. Obviously you can’t personally throw it but say you had some sort of mechanical device that was doing it, how much force would be needed? I changed the numbers because I wanted to see the effect of higher weight and limited...

Say you have a platform, and on that platform you have an object the weighs 10,000lbs (ignore the weight of the platform itself). If the platform is only allowed to move vertically 6” before it must stop moving, how much upward force would be needed to throw the 10,000lb object 12” in the air...

http://www.cowtownsleepers.com/images/safetyhitch1.jpg Someone online was talking about this and they said it would increase braking performance by 50%. I started thinking that that may not be true. I wanted to ask about the actual physics around it to see what would really be the benefit if...

I have been looking at explanations of that and it still kinda confuses me. They say that with increase of load would decrease the friction but then why do drag racers try to get all the weight to transfer to the rear or do they put the engine in most supercars in the back to get more weight...

I was simply stating that all brakes were capable of locking up to imply that they are able to hit max grip in all tires, not that during the test they would lock up. All tires in the test would have ABS. So does that change your answer?

Forgive me if I have not posted this in the right place but I have a quick question. Say if you have a trailer on a truck, let's say a semi trailer, that has 2 axles on it. You measure the stopping distance from a certain speed. You then add another axle to the trailer that has brakes on it with...

What about all the cons I listed in post #10? I personally really don't want this to happen. I just was curious if it was even possible.

To me, even if you could get this to work, the only advantage would be the low speed maneuverability. Cons would be plentiful. Cost would be astronomical. I would be very concerned with reliability. Unless the ball can collapse a little, the contact patch would be tiny. If it can collapse, I...

So what you guys are saying is that this is actually possible? I really didn't think it was. If this is possible, the only advantage would be the maneuverability at low speed. I can think of many disadvantages.

I hope I am posting this in the right place but forgive me if I am not. I randomly came across this video and was wondering if this is even possible. I have limited knowledge on this but I have a few thoughts as to why this would not work. First, would you not have to have a power supply in...
