TM 164 Coil spring vibrations
In helical springs, the spring force is generated by the elastic deformation of a metal band wound in an Archimedean spiral. If a mass is attached to the spring, we refer to it as a spring–mass system. The resistance that the spring presents opposite of the elastic deformation is known as spring stiffness. It is a characteristic variable of the spring.
The TM 164 unit comprises a helical spring connected to a rotating lever. Masses can be attached to the lever at various distances. This creates a spring-mass system, which can be used to study the effects of the spring stiffness, mass and mass distribution on the oscillation frequency. The deflection angle can be read on an angle scale.
The experimental unit is designed to be fixed to a wall.
