Question

Determine the resultant of the coplanar forces 100 N,0° and 200 N,90

Answer 1

Answer:

Explanation:

The two forces, with direction taken from North are F1 = 200 N st 60° to the East, and F2 = 85 N at 70° to the West.

Taking components of each Force

F1 (N) = 200 cos 60 = 100 N and F1 (E) = 200 sin 60 = 173.2 N

F2 (N) = 85 cos 70 and F2 (W) = 85 sin 70

Now you need to add those but remember that the two F2 components are in opposite directions.
