Resultant of Non coplanar concurrent force system:

How do you find resultant of Non coplanar concurrent force system?

Sol.: The resultant of non concurrent force system is that force that will have the same rotational and translation effect as the given system of forces; it may be a force, pure moment or force and moment.

R = {( ∑ H)² +(∑V)2}^1/2

tanθ    =     ∑V/∑H
∑M = R . d

Where,

H  = Sum of all the horizontal component

V = Sum of all the vertical component

M = Sum of moment of all the forces

d  = Distance between the resultant force and the point where moment of all the forces are taken.
