^You forgot the other second...

Velocity is measured in m/s, and acceleration in measured in m/s squared, or m/s/s. This is because when you are accelerating you are increasing your velocity which is in m/s by a certain amount every second, thus m/s/s

Easy example...

If your acceleration is 2 m/s/s, your velocity is increasing by 2 every second. So if you travel for 3 seconds your velocity is 6 m/s, and if your travel for 10 seconds, your velocity is 20 m/s...

^^Thanks! Everything is pretty understandable. I attempted making it when there was only half of the tutorial, but I epicly failed. I'm just saying that I had some idea of what I was building this time around. The only part the had me confused was when you put the rubberband on the trigger. The picture made it look like the rubberband was supposed to pull the trigger up and not down, but then I looked really close at the picture and saw that the rubberband goes over the blue rods that catches the chain.

With the 5 car train, the launch definitely, well, launched it, but not jesper launch material.

^^Thanks Rct2123, now I understand.

I see what you mean by adding the rubber band. But don't forget there's actually readable text on the left;)
And what do you mean with "not jesper launch material"?

^*goes back to tutorial*...*slaps head* OK, thanks...

I meant I've seen a working jesper launch and the 5 cars didn't go as fast.

As fast as this five car train ?
I thought Jogumpie had driven it to the extreme, now you're telling me you made it faster! :confused:
Please, do share your secret:D

[KCB Designs]

Can someone post the heights that the amount of cars/train can reach? Like the height of an X-amount car train can reach.

[knexems]

^^No, sorry, I was talking about my cars not going as fast. Yeah' Jogumpie's is wayyyy faster than mine.

It's OK. I misinterpreted it, I guess my enthusiasm overrated when I read your post above and it made me think you made it faster.

Here's what I think:
By moving the bottom wheel towards the end of the launch, the stretch-size will increase, but the chain can't move more.
By moving the trigger mechanism more towards the end of the launch, you can get the chain part where the rubber band is connected to more towards the end of the launch. That means it will be stretched more, and it can move (if you trigger the launch) more. (To its position where the rubber band isn't stretched).

So instead of moving the wheel towards the end of the launch, I suggest you should try to move the trigger towards the end. I moved it yesterday, now it's 6 red rods away from the long black rod. I haven't made test rounds with a train on but to my eyes, the chain accelerates faster!

EDIT: Luckily for you, knexems, the push mechanism is coming soon. (I think it will be on this Wednesday.)

[Jesperdude]

Ok here's the push mechanism!



It says that you have to adjust some steps from the official launch tutorial, but I think I made that clear.



















Yeah, I was in a yellow mood today.
Comment!

[spousl16]

Simply amazing!

I love how you added that little loading station to the launch. It gives the whole thing a much nicer appearance.

[Jesperdude]

^Thanks. And I agree, it looks nicer, and it makes it more comfortable though.


And notice:

[the_burrito_master]

nice! I love it. but I don't know how it works exactly.

[Jesperdude]

Look at the videos on page two. It shows exactly how it works.

[moosey124]

YOU ARE A PURE GENEOUS! You are officially my k'nex idol(yes i started to build again). Have you thought of making one of these but in an inlcine so going up?

[SwimZONE]

Blue Rod*2=Red Rod
Red Rod=Diagonal of Yellow Rod
Yellow Rod=Width of Launch.
It's practically built for that...

[~stεεlspectrum~]

^^ Dude...all you have to do is turn it. Add a support tower, and you've got an inclined launch
^^^^ It's a fairly simple concept. A rod holds the chain back, then it is released, and the chain flies forward.

[the_burrito_master]

^ I was talking about the loading station thing. I just figured it out that you push down the little knob.

[moosey124]

About how many of each piece does this use? do you have a list that you can maybe please post?

[Cardsandcoasters]

Is it possible for this to be shortened to about half the length or less? And does the base rod (blue) matter? Just thinking for planning future coasters.

[DeAzncy]

^that's what i wanted to know. the launch on Requiem doesnt have to be as long as the normal launch.
