The definition of torque is τ= r x F
Let's consider a disk that is rotating around his axis of symmetry, we are usually used to calculate the torque applied by a tangential force at the disk using as r the radius of the disk, but can I define a torque of the force using as r the generic distance between a point external of the disk? In this case will be the torque by this point different by the one referred to the axis of rotation? In my opinion yes because it's the most logical thing
Can we define a torque in a non rotation situation? Think at a particle that is pulled by a force in a uniform accelerated motion, according to the definition of torque we can choose a point in space and get the distance between that point and the force and get a torque, is that right?
