You have 8 ball bearings and a set of tip scales
All 8 ball bearings are the same size and colour
Except one of the ball bearings is lighter than the rest
You’re only allowed to weigh the ball bearings twice
to find out which ball bearing is the lightest
How do you do this

you only put 3 balls on each side of the scale. if the scales balance you know that the lighter ball is still in your hand, use your second weighing to assess which one is the lightest.
if on your first weigh your scales don't balance, take the 3 balls that appear to be lighter and place 1 ball on either side of the scales to see which is the lightest, if they balance then you have the lightest still in your hand.

As changed into stated above, the more advantageous ball bearing the smoother the reel will be, image a round rail with 2 ball bearing in it, and picture about the position the weak spots must be for rotation, no longer make that particular same rail have 8 ball bearings, and picture about what merely got here about to the weak spots you had at the same time as there have been in reality 2. no longer in reality have you ever eradicated some torision ability, yet you actually have 4 circumstances the lubrication aspect having 4 circumstances as many bearings.
