In this problem we seek to compute the rotational inertia of a disk of mass M and radius R about an axis through its center and perpendicular to its surface. Consider a mass element dm in the shape of a ring of radius r and width dr (see Fig). (a) What is the mass dill of this element, expressed as a fraction of the total mass M of the disk? (b) What is the rotational inertia dI of this element? (c) Integrate the result of part (b) to find the rotational inertia of the entire disk.

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.
