A of students conducts an experiment with an object made of two uniform disks, each of radius R, group and a thin axle. The disks are connected to each other with the axle at their centers and set on a horizontal table as shown in the perspective view above. The object has a mass M and total rotational inertia I about the axis of rotation as shown. A light string is tied loosely to the axle such that the string exerts a force without wrapping around the axle. Friction between the axle and string is negligible. The string then passes over an ideal pulley and is tied to a block of mass m=1.0kg. At time t=0 the object-block system is released from rest, and the block accelerates downward. In this case, the object rolls without slipping on the table. The coefficients of static and kinetic friction between the object and table are Us and Uk respectively.

Free Body Diagram

The system of forces acting on a body tends to either rotate it or make the body undergo motion. In general, when an external agent exerts a force on a body, the body undergoes translational motion and rotational motion. The body has six degrees of freedom under the influence of that force. Here, three degrees of freedom are from the translational motion while the other three are from the rotation motion. However, sometimes the bodies are not allowed to undergo any motion and are fixed, under such conditions the body is said to be constrained.

Question

A
of students conducts an experiment with an object made of two uniform disks, each of radius R,
group
and a thin axle. The disks are connected to each other with the axle at their centers and set on a horizontal
table as shown in the perspective view above. The object has a mass M and total rotational inertia I about
the axis of rotation as shown. A light string is tied loosely to the axle such that the string exerts a force
without wrapping around the axle. Friction between the axle and string is negligible. The string then
passes over an ideal pulley and is tied to a block of mass m=1.0kg. At time t=0 the object-block system is
released from rest, and the block accelerates downward. In this case, the object rolls without slipping on
the table. The coefficients of static and kinetic friction between the object and table are Us and Uk
respectively.
