The forces 3,4 and 7H act on the body along one straight line. What values can the resultant

The forces 3,4 and 7H act on the body along one straight line. What values can the resultant of these three forces take?

Data: F1 (value of the first force) = 3 N; F2 (value of the second force) = 4 N; F3 (third force value) = 7 N.

1) All three forces are co-directed: F = F1 + F2 + F3 = 3 + 4 + 7 = 14 N.

2) The first and second forces are aligned: F = F1 + F2 – F3 = 3 + 4 – 7 = 0 N.

3) The first and third forces are aligned: F = F1 – F2 + F3 = 3 – 4 + 7 = 6 N.

4) The second and third forces are aligned: F = -F1 + F2 + F3 = -3 + 4 + 7 = 8 N.
