Chapter 5. Torque and Rotational Equilibrium
5-14. Two wheels of diameters 60 cm and 20 cm are fastened together and turn on the same axis as in Fig. 5-14. What is the resultant torque about a central axis for the shown weights?
5-15. Suppose you remove the 150-N weight from the small wheel in Fig. 5-14. What new weight can you hang to produce zero resultant torque?
