As in figurc mass $m_{1}$ slides on the smooth horizontal sur[acc. The pullcy is rough and heavy in the form of a cylinder of mass $M$ and radius $R$ and string turns the pulley without slipping. Find the accelcration of cach mass, and tension in cach part o\lceil the string.

Key Concepts

No-Slip Condition

The no-slip condition ensures that there is no relative motion between the string and the pulley, implying a fixed relationship between the linear acceleration of the masses and the angular acceleration of the pulley. This constraint is crucial in solving problems where the string and pulley move together without slipping.

Tension in the String

When dealing with pulley systems, particularly with a massive and rough pulley, the tension in the string can differ on either side. This disparity in tension is responsible for the net torque on the pulley and must be carefully analyzed to relate the forces acting on the connected masses.

Newton’s Second Law

This law establishes that the net force acting on an object is equal to the product of its mass and acceleration. It is fundamental in analyzing both the linear motion of the masses and the rotational motion of the pulley by applying the law to each component of the system.

Rotational Dynamics

In systems that involve rotation, such as a heavy cylindrical pulley, the principles of rotational dynamics are essential. This area explores how torque causes angular acceleration, analogous to how net force causes linear acceleration in translational motion.

Moment of Inertia

The moment of inertia is a property that quantifies an object’s resistance to changes in its rotational motion. For a cylindrical pulley, it determines how the distributed mass affects the angular acceleration under the applied torques from the differing tensions.
