Triple Beam Balance...?

Question

How are the three beams on a triple-beam balance different?

Answer 1

To make rhsaunders excellent answer slightly more correct, the 'weights' have different masses. This, or any balance, is better than any scale because (1) it is independent of the strength of gravity, so it works equally well at sea level, on a mountain top, or on the moon. A gram always balances a gram. and (2) a 'weight' can be manufactured with a specific mass very accurately, and it's very stable. As far as I know, no scale has ever achieved this.

Answer 2

The triple beam balance is a rugged, inexpensive weighing instrument. It is named for the three beams which carry weights.
A. The middle beam reads only in 100 g increments.
B. The far beam reads only in 10 g increments.
The weights in each of these must always sit in a "notch". They cannot be placed at arbitrary points on the beam.
C. The weight on the front beam can be placed to read continuously from 0 to 10 grams.

Answer 3

They carry different weights. The two beams with the heavier weights have detents, such that the weights can occupy only certain positions. The other beam has no detents, so the weight can be slid along the beam until the scale is in balance. The weight positions on the three beams are then added to get the weight of the sample.

Answer 4

Not sure but I Loved the beam balance when I was in school lol

Answer 5

the weights on each beam is related to what it is suppose to measure.

Answer 6

if your using the same one as me (with tan colored weights i think) it is two decimal places, so the total number of sig figs depends on what the mass is 1.00g, 10.00g, 100.00g,

Answer 7

Yes.
