so you mean that the point of contact between pulley 5 and branch A has a zero velocity? (a center of instantaneous rotation?Lnewqban said:

The angular velocity of a rotating drum can be calculated by dividing the angular displacement by the time it takes to complete one rotation. This can be represented by the formula ω = Δθ/Δt, where ω is the angular velocity, Δθ is the change in angular displacement, and Δt is the time taken.
The unit of measurement for angular velocity is radians per second (rad/s). This is because angular velocity is a measure of how quickly an object is rotating, and radians are a unit of measurement for angles.
The mass of the drum does not directly affect its angular velocity. However, the distribution of mass within the drum can affect its moment of inertia, which is a factor in the calculation of angular velocity. A drum with a larger moment of inertia will have a lower angular velocity for a given amount of torque applied.
Yes, the angular velocity of a rotating drum can change over time. This can happen if there is a change in the applied torque, the distribution of mass within the drum, or the surface on which the drum is rotating. Changes in angular velocity can also occur due to external forces such as friction or air resistance.
Angular velocity and linear velocity are two different measures of an object's speed. Angular velocity is a measure of how quickly an object is rotating, while linear velocity is a measure of how quickly an object is moving in a straight line. Angular velocity is typically measured in radians per second, while linear velocity is measured in meters per second.
