1. The problem statement, all variables and given/known data The force F = (15x - 22y)N is applied at r = (4.0x + 7.0y) meters. What torque (about the origin) does this force produce? 2. Relevant equations Torque = r * F * sin theta r = magnitude of radius, F = magnitude of F, theta = smallest angle between the directions of r and F 3. The attempt at a solution I was wondering what "about the origin" was referring to. Theoretically, shouldn't I be able to find the magnitudes of F and r with (ax2 + ay2)1/2 and the angles they make with the positive x axis with (tan theta = ay/ax) and then figure out the smallest angle between them from that and calculate the torque? Is it just saying the origin is the rotational axis so I don't have to worry about trying to translate the equations to some other rotational axis?
