Electric Circuit and Components

An electrical circuit or electrical network is a pre-determined pathway to make the electrons flow in the desired direction. The flow of electrons will set up a current flow in the circuit. Normally, the flow of electrical current is opposite to the flow of electrons. An electron is a fundamental sub-atomic particle of an atom possessing a negative charge. To initiate the flow of current and achieve the desired output, the electrical circuit should necessarily be composed of closed pathways. The pathways are made-up of good conductors of electricity such as aluminium and copper.

The bar shown rotates about a fixed axis through point $O$. At the instant shown, the bar has angular velocity $\omega$ [rad/sec] and angular acceleration $\alpha$ [rad/sec$^2$]. Determine:

1. The velocity $v_A$ [m/sec] of point A
2. The acceleration $a_A$ [m/sec$^2$] of point A

**Diagram Explanation:**

The diagram illustrates a bar of length $L$ that rotates counterclockwise about a fixed point $O$. The bar is inclined at an angle $\theta$ from the vertical. The rotation axis is fixed, and the bar is shown at the position where it makes this angle $\theta$. The following elements are depicted in the diagram:

- **Point $O$**: The fixed point about which the bar rotates.
- **Point $A$**: The end of the bar, a distance $L$ from point $O$.
- **Angular Velocity ($\omega$)**: Shown as a green circular arrow indicating the rate of rotation.
- **Angular Acceleration ($\alpha$)**: Shown as another notation beside $\omega$.
- **Length $L$**: The total length of the bar from $O$ to $A$.
- **Angle $\theta$**: The angle between the bar and the vertical direction, marked on the bar.

The rotational motion involves both angular velocity ($\omega$) and angular acceleration ($\alpha$), which affect the linear velocity and linear acceleration of point $A$.
