The situation in which the magnitude of the total force is greater than the magnitude of each individual force is:
Two people stand on the same side of a large box. One pushes, and the other pulls with the same amount of force.
In this scenario, the two forces are acting in the same direction (the push and the pull effectively combine), resulting in a total force that is the sum of the individual forces. This is different from the other scenarios where forces are balanced or acting in opposite directions, which would either result in no net force or a smaller total force.
