To solve the problem, we need to determine the weight indicated on each triple beam balance. A triple beam balance consists of three sliding weights (beams) that can be moved along calibrated scales. The weights are typically labeled as follows:
1.
Large Beam: Usually in increments of 100 grams.
2.
Medium Beam: Usually in increments of 10 grams.
3.
Small Beam: Usually in increments of 1 gram.
Step-by-Step Solution:
####
1)
-
Large Beam: The slider is at 0.
-
Medium Beam: The slider is at 0.
-
Small Beam: The slider is at 0.
-
Total Weight: \( 0 + 0 + 0 = 0 \) grams.
####
2)
-
Large Beam: The slider is at 100.
-
Medium Beam: The slider is at 50.
-
Small Beam: The slider is at 0.
-
Total Weight: \( 100 + 50 + 0 = 150 \) grams.
####
3)
-
Large Beam: The slider is at 200.
-
Medium Beam: The slider is at 30.
-
Small Beam: The slider is at 5.
-
Total Weight: \( 200 + 30 + 5 = 235 \) grams.
####
4)
-
Large Beam: The slider is at 300.
-
Medium Beam: The slider is at 70.
-
Small Beam: The slider is at 8.
-
Total Weight: \( 300 + 70 + 8 = 378 \) grams.
####
5)
-
Large Beam: The slider is at 400.
-
Medium Beam: The slider is at 90.
-
Small Beam: The slider is at 3.
-
Total Weight: \( 400 + 90 + 3 = 493 \) grams.
Final Answers:
1. \( \boxed{0} \) grams
2. \( \boxed{150} \) grams
3. \( \boxed{235} \) grams
4. \( \boxed{378} \) grams
5. \( \boxed{493} \) grams
Explanation:
Each beam's slider position is read directly from the scale, and the values are added together to get the total weight. This method ensures accuracy in measuring the mass using a triple beam balance.
