This is a problem in my homework. My friend and I have been working on it for the past week and cannot match the answer to the back of the book. I think my main problem is I don't understand what it is trying to say about the dimensions of the force P. The 5 degrees and the 70 degrees doesn't really make much sense. I know that if I could get the vector from point A to C and the components of the force then it would be easy. The hard part is I don't know how to find either of these. I tried using the method in Calculus 3 of converting spherical coordinates to cartesian and that didn't get me anywhere. Please help me interpret this graph. There was another problem after this one that I had to use this picture for and I was able to get it. It took me probably about a full day to get it, but I finally got it. Basically in that one I just had to find the perpendicular distance to point C which came out to be 8.07 in.(adsbygoogle = window.adsbygoogle || []).push({});
