Harmonic oscillations of spiral springs with CobraSMARTsense
Principle
The spring constant D is determined for different experimental set-ups from the oscillation period and the suspended mass.
Benefits
- Large and sturdy set-up suitable for demonstration and lab courses as well
- Data logging reveals instantaneous results during measurement
