Two forces 20N and 8N, acting along one straight line in different directions

| May 10, 2021 | education

Two forces 20N and 8N, acting along one straight line in different directions, are applied to the same body, determine the resultant force.

Given:

F1 = 20 Newton – the magnitude of the first force;

F2 = 8 Newton – the magnitude of the second force.

It is required to determine F (Newton) – the resultant of two forces.

According to the condition of the problem, both forces act along one straight line in different directions. Then, we introduce a coordinate system and assume that the force F1 acts in the positive direction of the ОХ axis, and the force F2 – in the negative one. The resultant of the two forces will be equal to:

F = F1 – F2 = 20 – 8 = 12 Newtons.

Answer: the resultant of two forces will be equal to 12 Newtons and directed towards the greater force.
