can you please explain how this is the
answer
A wheel of outer radius R has four forces, each of magnitude indicated, acting as shown. It is free to pivot about its center. Say it has moment of inertia I. Two of the forces are acting a distance R/2 from the pivot. What is the equation of motion for the wheel in terms of tangential acceleration at the edge of the wheel (a), knowing that a solid disk has the...
