Technical Description
This table unit is used to perform experiments on a spring-mass system. A low friction ball bearing mounted carriage can move between two ground guide pillars. Additional weights can be attached to the carriage; the carriage is suspended on a helical spring. The zero position can be adjusted using a threaded spindle at the top of the spring. The guide pillars are attached to a strong cast metal base with handles. To damp the vibrations, an oil-filled liquid damper is provided. The continuous connecting rod moving in spherical liners without a seal ensures even, direction-independent damping with only minimal Coulomb friction. A mechanical drum recorder with chart paper enables the vibrations to be recorded using a fibre pen attached directly to the carriage.
Learning Objectives / Experiments
· Determination of the stiffness of a helical spring
· Determination of the natural frequency of a naturally oscillating spring-mass system
