According to Lami's theorem

Three forces acting at a point will be in equilibrium

Three forces acting at a point can be represented by a triangle, each side being proportional to force

If three forces acting upon a particle are represented in magnitude and direction by the sides of a triangle, taken in order, they will be in equilibrium

If three forces acting at a point are in equilibrium, each force is proportional to the sine of the angle between the other two

Correct Answer : If three forces acting at a point are in equilibrium, each force is proportional to the sine of the angle between the other two

The structures constructed along are distributaries are called as _______

Inlets

Outlets

Channels

Distributaries

Correct Answer : Option (B) : Outlets

Explanation : An outlet is a simple and small irrigation structure which is constructed along the distributaries. The amount of water that is withdrawn through the outlet is in proportion to the area that is irrigated below respective point.
