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.
