Question

4. The diagram shows two masses, ml and m2, that are connected by light cables as shown in the diagram above. They are connected about the perimeters of two cylinders of radii r and r, respectively, as shown in5m the diagram above with r-0.5 meter, r2- 1.5 meters, mi- 20 kilograms, and m-25 kilograms. Axle a. In the space below, draw a force diagram showing all of the forces acting on the masses. mass 1 mass 2 -20kg b. i. Write a true statement comparing the torque of mass 1 to the torque caused by mass 2. In a sentence, justify your reasoning why this statement should be true. ii. What can you say about the rotational acceleration of cylinder 1 compared to the rotational acceleration of cylinder 2? c. When released the heavier block falls 50 cm in 4 s. Determine the magnitude of the blocks' acceleration? d. If you want the system to be in equilibrium, what value should you replace mass 2 with to achieve equilibrium?
