Size:  5.6 KBI'm not sure where I'm going wrong - to find the vertical component of the force f, the answer is to do f*sin(30). But in my workings, sin(30)=d/door, so I'm not sure how f would come into it.

    If you're interested in finding the vertical and horizontal components of the force F, the length of the door or the perpendicular distance d doesn't matter. You could just draw a force diagram on its own with the door as a horizontal.. but then again you haven't posted the question, just that you're trying to find the components so..
