Thread oscillation with Cobra SMARTsense

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.
