There are three forces in common, which are 2n, 7n and 8N. What are the maximum and minimum of their resultant forces

The maximum value is 17N and the minimum value is 0 I won't elaborate on this Now let's focus on the minimum First consider two smaller forces 2n and 7n. The maximum resultant force of these two forces is 9N and the minimum is 5N, because 9N > 8N > 5N Therefore, we must be able to make the two forces 2n and 7n form an angle to make the resultant force 8N, so as long as we make the greatest force in the opposite direction of the resultant force, we can make the resultant force of 2n, 7n and 8N 0
