SW-2598 - ESAW Forced Oscillation Demonstrator 

For the study of resultant v vibratory moon (forced) produced on account of oscillations of two coupled springs. Two springs, each having different spring constants (hence different natural frequencies of vibration), are attached vertically to each other through a cylindrical mass and the assembly is supported at the top on adjustable support. The lower spring also has a weight attached to its lower end, which is guided inside another adjustable support. The release the mechanism on the base, when releases the lower mass, both the stretched springs show their independent oscillations, influencing the moon of one another. Complete assembly mounted on a stable base.
