Principle
By plucking a rope, vibrations are excited on it. These are acoustically perceptible, similar to a guitar, and cause a periodic change in force at the suspension point of the rope.
Benefits
- Especially understandable and didactically prepared description of the experiment (relevance to everyday life, etc.) including protocol questions.
- Future-oriented teaching: Integration into digital science lessons with tablets or smartphones.
- Increased motivation of students by using the intuitive measureAPP.
- Increased media competence.
Tasks
- Stimulate vibrations on the thread by hand and perceive them acoustically for different rope tensions.
- Measure with the help of the force sensor the vibration of the thread for different tensions.
Learning objectives
The students should excite vibrations on a thread and learn how the period and frequency depend on the tension in the thread.
