Hi all, If Torque = Arm cross Force Is it possible to calculate the arm from the torque and the force? I have tried to solve this using cross product of torque and force to give me the arm direction. Then normalizing the result and multiplying by torque magnitude / force magnitude. However I am guessing this is wrong as it doesn't take into account only the component of the force vector that is generating a torque. I am also wondering if this is even possible or if there are many solutions? I essentially have a resulting force and torque and would like to work backwards from this to find the point at which the force was applied. Any help much appreciated!
