Hello


how do we get the resultant force of a vector id the the forces were in different directions ?


and how do we use the parellogram thingi


do we just add the forces?



please can some1 explain me this in their own words



thanks alot

Since this is not my area of expertise, I searched Google under the key words "vector force resultants" to get these possible sources:

There are other sites available, if you want to continue the search.

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. Thanks for asking.

ok make the parallelogram and then make the resultant...then if you have an agle, the other side must be 180-given angel....so then use the law of cosines to figure out the length of the resultant!

a^2= b^2+c^2-2bcCosA
