The three forces are 68.12n, and the resultant force range is calculated

The three forces are 68.12n, and the resultant force range is calculated

When the three forces are on the same line and in the same direction, the maximum resultant force is: F max = 6 + 8 + 12 = 26 (n)
When the resultant force of 6N and 8N is equal to 12n and the direction is opposite to 12n, the resultant force is the smallest, that is, f = 0n
Therefore, the range of resultant force is 0n ≤ F and 26n
