- Homework Statement
- Using Resultant Forces By Connecting Vectors Head To Tail

- Relevant Equations
- NA

Hi all

I am trying to get my head around resultant forces.

I am happy that if I have a vector diagram with 2 forces I can work out graphically the resultant forces by connecting the head of one of the vectors to the tail of the second vector.

The confusion comes in when I have 3 or more vectors, for example the vector diagram has 3 forces and I am trying to figure our the resultant for graphically.

My resultant force changes depending on the order I connected the 3 vectors, the different shapes I get when I connect the vectors is as follows:-

Is there a set convention that is used when connecting vectors head to tail to determine the resultant?

Can you help?

Thank you.
