If a number of forces are acting at a point, their resultant will be inclined at an angle θ with the horizontal, such that
tan θ = ∑H/∑V
tan θ = ∑V/∑H
tan θ = ∑Vx∑H
tan θ = ∑V+∑H
Forces are called coplanar when all of them acting on body lie in
One point
One plane
Different planes
Perpendicular planes
The resultant of two forces P and Q (such that P > Q) acting along the same straight line, but in opposite direction, is given by
P + Q
P / Q
Q / P
P - Q
Lami's theorem states that
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 at a point are in equilibrium, each force is proportional to the sine of the angle between the other two
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
