Does anyone have an intuitive explanation for why torque depends on the perpendicular distance from the axis of rotation? I understand the maths and fully accept the truth of the description, but CANNOT wrap my brain around the reason. The ball and spring model of a solid seems like a place to start? The uneven acceleration of a body's particles must play a role, since this is what defines rotational motion. References to conservation of energy seem to simply beg the question. In terms of the various linear tendencies of component particles, how does an increase in radius actually change the distribution of force on a body?
