I have a two-part problem. The first part gve me a position vector r and a Force vector F acting upon r and I needed to find the magnitude of the torque about the origin. I took rxF and got the correct answer. Part two asks me to find the torque about the a new point (a,b). So instead of r rotating about the origin, it is now rotating about (a,b)? I was okay with the first part, but I just don't understand what's going on with the second part and how to attempt it. I was thinking of a few things regarding the distance between the origin and (a,b) and crossing that with F ... I just don't know what to do ... help! :D Thanks in advance, you guys are always terrific!(adsbygoogle = window.adsbygoogle || []).push({});
