First tell us the size of the bolt- they all have different weights. There are some in my shop that weigh about 10 grams, some that weigh about 200. I work with some cranes that have bolts that weigh about 10,000 grams.
2.5 grams = 0.0881849049 ouncesI've got the formula for you-2.5 g*1 oz28.34952313 g=0.08818490487 oz
189 millimeters is 18.9 centimeters.
grams----------------------------------- it should weigh(if it's new)5 grams
On some simple platform scales (for example) the test weights are fitted to a suspended plate. The weights themselves have a 'radial' slot to accommodate the suspending rod. You could also consider the weights to form a crude letter C. In any event, the effect is that the test weights have their centre of mass approximately central, thus the suspending rod is close to vertical.
