is a square that has a side length of cm.
where cm. Given that forces
of magnitudes 8, 20, ,
and 12 newtons act in the directions of ,
, , and respectively,
find the magnitude of their resultant.
Draw a diagram of the problem.
Firstly, calculate using trigonometry.
Resolve the forces horizontally and vertically to find the resultant.
Find the magnitude of the resultant.
