torsional oscillations of a spring-mass system

Description:

• 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 164unit 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.
