# What is the resultant of two forces of 600 N each forming an angle of 120 degrees?

September 18, 2021 | education

| Initial data: F1 (first acting force) = F2 (second acting force) = 600 N; α (angle, which are formed by the vectors of acting forces) = 120º.

The resultant of the two acting forces is determined using the trigonometric method of adding vectors: F = √ (F1 ^ 2 + F2 ^ 2 – 2F1 * F2 * cos (180 – α)).

Let’s perform the calculation: F = √ (600 ^ 2 + 600 ^ 2 – 2 * 600 * 600 * cos (180 – 120)) = 600 N.

Answer: The resultant of the two acting forces is 600 N.
