Final answer:
To find the tension in each strand when a bag is supported by 3 vertical strands, divide the total weight of the bag by 3. If the bag weighs 90 N, the tension in each strand would be 30 N.
Step-by-step explanation:
To determine the tension exerted in each strand when a bag is supported by 3 vertical strands, we assume the weight of the bag is evenly distributed across all three strands.
To find the tension in each strand, we would divide the total weight of the bag by the number of strands.
For example, if the bag weighs 90 N, then each strand would support one-third of the total weight because the tension is evenly distributed.
Therefore, the tension in each strand would be:
Tension per strand (T) = Total weight / Number of strands
T = 90 N / 3
T = 30 N
So, each strand would have a tension of 30 N.
