A simple harmonic oscillator is created by attaching a spring with a spring constant of 584 J/m2, to two blocks as shown in the figure. The mass of block A is 6.3 kg, the mass of block B is 8.5 kg, the mass of the pulley is 4.2 kg. 04 = 34°, and 0B -42°. The pulley can be modelled as a uniformly dense solid cylinder rotating around an axis through its center. All surfaces are frictionless, the pulley is frictionless, and the rope passes over the pulley without slipping. What is the angular frequency (in rad/s) of oscillations of this system? BA m 08

Moment of Inertia

Inertia can be termed as a resistance offered by a body to change its state. A rigid body initially at rest will apply resistance when acted by an external force that tends to change its state of rest or velocity, or a body initially at motion will provide resistance in changing its state of velocity or motion for coming to a state of rest. In other words, Newton's first law of motion describes the law of inertia of a rigid body.
