iamded Posted June 16, 2007 Posted June 16, 2007 I saw these two catapults and wondered if the seller had created them himself or just took them off a set to sell. Does anyone recognise these from a set? I think the design is rather unique, I havn't seen it before. Credit to 'dseller' for picture. Quote
oo7 Posted June 16, 2007 Posted June 16, 2007 10176 contains three of them. It's sort of funny, if you pull it back too far it does not shoot shoot as far as it would if you were to pull it a slight bit...... If you live in the US, Shop at Home has marked them it down 50% to 50USD. http://eurobricks.hosting.ipsyn.com/eurofo...?showtopic=9948 Quote
iamded Posted June 17, 2007 Author Posted June 17, 2007 Ugh, not that set! I have the original, much better. It's hard to replicate something if you use a different baseplate. :-/ Quote
trooperdavinfelth Posted June 17, 2007 Posted June 17, 2007 (edited) 10176 contains three of them. It's sort of funny, if you pull it back too far it does not shoot shoot as far as it would if you were to pull it a slight bit......Why? Because it is naturally diagonal. If you pull it back too hard, you will shoot it more or less straight up. If you pull it back naught but a little, it will fly more or less diagonal, or straight forward.

It has a dragon, skeletons, lots of shiny silvery knights, an awesome king, and hopefully some nice catapults. Edited June 17, 2007 by trooperdavinfelth Quote

If you pull it back naught but a little, it will fly more or less diagonal, or straight forward. Nope, in both instances the projectile travels across the trajectory perpendicular to the point or release; where the catapult arm is stopped by the rubber band relieving the centripetal force caused by the motion of the arm. If you pull it back further, the opposite and equal action is greater creating more tension on the rubber band. This change sends the projectile at a closer angle relative to a flat, even surface. Thus, the projectile hits the ground sooner creating more fiction earlier than it would otherwise and depriving it of the kinetic energy required for it to stay in motion further. ;-) That's the advanced inertial analysis of Lego bricks.

iamded Posted June 18, 2007 Author Posted June 18, 2007 So... what's your analysis of the new Crossbow? I found it to shoot the bolt a pitiful distance. :-( Quote
