Forced Vibration and Resonance Demonstrator Key benefits Clear, hands-on demonstration of forced vibration and resonance: shows how an object vibrates under external forcing and how vibration behavior changes under specific conditions. Makes abstract concepts tangible: helps students and instructors visualize resonance, phase relationships, and amplitude changes without complex equipment. Ready-to-use and durable: simple assembly on a plastic frame with a stable stand for repeated classroom or lab use. What it contains Stand and plastic frame: stable mounting for demonstration and classroom handling. Five steel balls with different pendulum lengths: allow comparison of natural frequencies and observation of resonance across varying pendulum lengths. Single driven pendulum: provides the external forcing source to induce forced vibration in the attached system. Key attributes Function: Demonstrates forced vibration and resonance, including amplitude response to external forcing and behavior under varying conditions. Material: Steel balls for consistent mass and predictable dynamics; plastic frame for lightweight, durable mounting. Compatibility: Designed for physics teaching and laboratory demonstration contexts; suitable for high school and undergraduate physics labs, science demonstrations, and instructional displays. Performance: Enables direct observation of resonance effects and comparative experiments using five different pendulum lengths. Why customers need this Simplifies instruction: Converts theoretical material into visible, repeatable experiments to accelerate learning and retention. Saves setup time: Pre-configured components (stand, pendulums, steel balls) reduce preparation and allow instructors to focus on concepts and measurements. Versatile teaching aid: Useful for demonstration, student experiments, and as an illustrative display in a lab setting. Use scenarios Classroom demonstration: Instructor drives the pendulum and compares the responses of the five steel-ball pendulums to show resonance peaks and phase shifts in real time. Laboratory experiment: Students measure amplitude and frequency relationships for each pendulum length to quantify natural frequency and forced response. Educational display or decor: Mounted on a plastic frame and stand, it can serve as a permanent visual aid in a physics lab or science center to reinforce learning between lessons. What to expect in practice Easy setup and stable operation on a tabletop or lab bench. Repeatable outcomes for demonstrations and simple experimental data collection. Clear visual contrasts between different pendulum lengths to support instruction on frequency dependence and resonance conditions.
