I'm creating a logo and want it to be as exact as possible.

The logo idea is a "Newtonian cradle", but with only 2 balls and on straight steel wire (can't be bend).

What would happen if I dropped these as in the image from the same height, at the same time ?

Newton's cradle

  • $\begingroup$ Provided the wire is rigid,the two balls will strictly fall vertically downwards under gravity till the wire becomes taut. $\endgroup$ – user36790 Jan 20 '15 at 9:02
  • $\begingroup$ Yes, but if they were locked on a steel wire on that fixture point in the middle, which they could rotate around. Would they rotate down and work like newton's cradle, where they bump each other around, or would they simply stop? $\endgroup$ – Andreas Münter Jan 20 '15 at 9:08
  • $\begingroup$ For rotation, torque must be present. $\endgroup$ – user36790 Jan 20 '15 at 9:14
  • $\begingroup$ I have tried to create an animation of how I think it would go down! www.designduck.dk/cph/newtons/sales-training.html $\endgroup$ – Andreas Münter Jan 20 '15 at 9:15
  • $\begingroup$ At any other position, it was imparted by the component of gravity. But at this position,torque becomes zero. Hence,they'll not rotate. $\endgroup$ – user36790 Jan 20 '15 at 9:15
