A $30$cm diameter disc mounted on a $10$cm axis. Diameter wheel without skating on a pair of inclined rails. A string is attached to the cylindrical surface of the disc. Of negligible mass from which hangs a block of $100$n$.$ The weight of the disc and axis is $375$n and its radius of rotation with respect to the axis of rotation passing through its center is $10\mathrm{.}6$cm$.$ SCM$.$ If the cylinder starts from rest on the bottom of the rails, determine the tension. Initial string, acceleration of the block and angular acceleration of the disk.

The radius of rotation is a value ri that allows us to calculate the moment of inertia of a round object, with respect to the axis passing through its center, for example a rim, such as l$\_\{$m$\}=(1/2)$ urj $\{2\}.$
