It is known that F1 = 6N F2 = 7n F3 when a body moves in a straight line with uniform velocity under the action of three different directions of common point forces =8N, what are the three resultant forces? What are the magnitude of the two resultant forces F1 and F2 in the N direction?

Three forces 0, 8N along 3F

The minimum value of the three common point forces F1 = 5N, F2 = 10N and F3 = 20n is 5N
What's the difference between the two problems?

According to the parallelogram rule of force, if three forces can be purchased into three sides of a triangle, that is, any side is less than the sum of the other two sides, and any side is greater than the difference between the other two sides. Or equal to, it is in a straight line, and the essence is the same
