Resultant force

Content

This can be defined as a single force which can produce the same effect as the combined force on a system.  The addition of two or more forces produces the resultant force. The resultant of any system of force can be obtained through any of the processes described earlier.

Equilibrant Force

This is that force which when added to a system of vectors will make the resultant of the system zero. Equilibrant has the same magnitude as the resultant force but it always acts in a direction opposite to.... View More
