The question is fairly easy, however the way they want the answer displayed is doing my head in.. Anyways the questions states
"replace the loading system by an equivalent resultant force (express your answer in terms of the unit vectors i and j)"
The question is a simple beam with forces along different sections, refer to the image I've uploaded to see what I'm talking about.
The Attempt at a Solution
I know that the resultant Force lies along the beam at the 2metre mark and the force at this particular point, is 6.25kN I believe...
Any help is greatly apprechiated, I'm a little new to the whole vector thing, so forgive me. Thanks in advance
