Three forces act along a straight line in one direction on the body: F1 = 50 H, F2 = 100H, F3 = 180H

Three forces act along a straight line in one direction on the body: F1 = 50 H, F2 = 100H, F3 = 180H, which is equal to the resultant of these forces

The resultant forces are the sum of all the forces acting on the body. Since in this case all forces act in one direction and along one straight line, the resultant of all these three forces will be equal to | F1 | + | F2 | + | F3 | = 50 + 100 + 180 = 330 N.
Answer: 330 N.
