Select the correct statement of Lami’s theorem.
1
If three forces acting on a body are said to be in equilibrium, then each force is directly dependent on sine of the angle between the other two forces.
2
If three forces are non-coplanar, then each force is directly dependent on sine of the angle between the other two forces.
3
If three forces are not in equilibrium, then each force is inversely proportional to sine of the angle between the other two forces.
4
If two forces are in equilibrium, then each force is directly proportional to sine of the angle between them.
