Life's a drag

Maximum speed is exactly that, the vehicle cannot go any faster, there is NO change in speed so no acceleration (which is the rate of change of speed) and as such weight has no effect.
If the vehicle starts to slow down ie decelerate then weight will have an effect. BUT, on a flat road, at the point where the speed is neither increasing or decreasing it has no effect.

I agree. But what I'm suggesting is that in real life weight (inertia) always plays a part because there will never be a time (perhaps not even a moment) when the true steady state situation applies. The speed will constantly change.

In a situation where the gradient goes downhill or the wind force changes to our advantage ( no matter how slight) the equation will work to our advantage and speed will rise. Next moment the opposite might happen. Basically I'm suggesting that conditions constantly change.

somewhere along here I lost the will to live......

RIP. SteveL.  Another member lost. Oh dear

Yeah and I've been reading these threads as well. If someone invites that 'expert' along you can count me out as well. Some people do talk a load of crap. The basic principles of weight, friction (in it's different guises) and power will always effect speed. School kids can understand that. Stop trying to confuse the situation. I will not even open this thread in the future. If you find this interesting, you've got a problem.......and before you question me I used to work as a Production Tooling Engineer (BAe Military Aircraft) and teach Science at Secondary school.
Get a life, go ride your bike and accept that if you cannot go fast, get a bigger engine!

PS I'm with SteveL on this.

yeah, it lost me some time ago 



Whatever happened to those traditional TC debate topics,

The flatulent effect of Jerusalem Artichokes?

Gas or petrol?

Lucy Verasamy ( Weathergirl)

Those I can keep up with!

Oh my goodness I dare anyone ?? A teacher, cos let's face it they are the font of ALL knowledge

Ok no problems. Good lucks guys.

Thankfully (I'd like to think) it's a relatively free forum. Opinions are part and parcel. Diverse opinions should, in theory, make life on here more interesting and stimulating.

It is nice if things are kept civil, but strong feelings should be listened to. Heckling, in an attempt to get people to stop posting things they don't like, for whatever reason, is a very weak and pathetic tactic in my eyes.

In the words of our very well established parliament . HERE HERE. Well said. Could,nt av put it better myself

I may be mistaken..... but I think that's what's been going on in this thread.... and like most threads...they run their course... with good, bad & indifferent comments...

so now we're all fed up with this one.... we'll start another on :De   ...   and life goes on.... well for us in the uk..... not for the poor sods on rotting hulks stuck in the Mediterranean sea .....

Off you go then. I would imagine that the same people who have come under attack would be the least likely to try to stand in your way.

According to the basic principles mentioned, there are alternatives to "a bigger engine". You forgot to mention that.

Who exactly are you adressing your comments towards? Surely you can't mean the whole thread is a load of crap?

Why not explain things your way?

Well, you'll be glad to know, I didn't invite my brother-in-law onto this thread. But that's mainly cause he's an arrogant t@@@

They want an input for weight.
