Resultant of Non-concurrent Force Systems

The parallel force systems are also non-concurrent force systems and hence can be reduced in the same way.

Resultant of Non-concurrent Force Systems

A system of non-concurrent forces can be reduced to:

1) A single moment if resultant force is zero.

ii) A force-couple system.

iii) A single resultant force with a specified line of action. The line of action can be specified by the perpendicular distance of resultant force from a given point or x/y intercept on co-ordinate axes or intercept on any inclined axis.

• The parallel force systems are also non-concurrent force systems and hence can be reduced in the same way.

• The resultant force can be obtained using resolution of forces into rectangular components.

• The line of action of resultant force can be obtained using Varignon's theorem.
