Task data: F1 (value of the first vector force) = 17 kN; F2 (value of the second vector force) = 22 kN; α (angle between vectors of specified forces) = 55º.
To determine the resultant of two given vector forces, we use the parallelogram rule: F = √ (F1 ^ 2 + F2 ^ 2 + 2 * F1 * F2 * cos 55º).
Let’s make a calculation: F = √ (17 ^ 2 + 22 ^ 2 + 2 * 17 * 22 * cos 55º) = 34.67 kN.
Answer: The required resultant of two forces is 34.67 kN.
