Question
The image illustrates a physical system involving a cart, spring, damper, and pendulum. The system consists of the following components: - **Spring (k)**: It is depicted on the left side of the cart, connected to both the cart and a fixed surface, indicating it exerts a force proportional to its displacement. - **Damper (b)**: Positioned parallel to the spring, the damper is also connected to both the cart and a fixed surface, representing a force opposing the cart’s motion (damping force). - **Cart (m₁)**: The cart has a mass labeled \(m_1\) and is situated on wheels, allowing it to move horizontally along the surface. The horizontal position of the cart is denoted by \(x\). - **External Force (f)**: An external force \(f\) is applied horizontally to the right side of the cart. - **Pendulum (m₂)**: Attached to the cart, the pendulum consists of a mass \(m_2\) suspended by a rod or string of length \(L\). The pendulum can swing, creating an angle \(\theta\) with the vertical. To analyze this system, the objective is to determine: - \( \xi \) (Damping ratio): A dimensionless measure describing how oscillations in a system decay after a disturbance. - \( W_n \) (Natural frequency): The frequency at which the system would oscillate if there were no damping and no external forces. - \( W_d \) (Damped natural frequency): The frequency at which the system oscillates when there is damping present. **Educational Objectives:** 1. **Understanding System Dynamics**: Learn how mass-spring-damper systems and pendulum dynamics interact. 2. **Calculating Damping Ratio**: Understand the concept of damping and its effect on oscillatory systems. 3. **Determining Natural and Damped Natural Frequencies**: Calculate these frequencies to understand the behavior of the system under various conditions. This depiction provides a comprehensive foundation for studying the interactions and forces within combined mechanical systems.
