The game consists of 25 levels. The objective of each is to get the wheel to touch the platform. The levels toward the end have two platforms, which require getting the wheel to touch both. I recommend starting each level with the simulation on first to see what happens – how each object reacts to the gravity and then tab through the objects to see which ones can be altered.

There are 10 achievements per level, which amounts to 25x10 = 250 in all. For each level, simply move an object around with the mouse for a few seconds to unlock all 9 of the In-Depth Analysis achievements. Then complete that level for the tenth achievement.
