Three forces act along a straight line in one direction on the body F = 50 N F2 = 100 N

Three forces act along a straight line in one direction on the body F = 50 N F2 = 100 N F3 = 180 N, which is equal to the resultant of these forces.

Since these three vectors are codirectional and lie on one straight line, then to calculate the resultant forces we apply the formula: F = F1 + F2 + F3.

The indicated forces: F1 – the first force (F1 = 50 N); F2 – second force (F2 = 100 N); F3 – third force (F3 = 180 N).

Let’s calculate: F = 50 + 100 + 180 = 330 N.

Answer: The resultant of the indicated forces, according to the calculation, is 330 N.
