Copper Calorimeter, 75 x 50mm Subcategory_Filtration Equipment a denser alternative to brass

a denser alternative to brass or aluminum for pendulum-period and simple-harmonic-motion work

and resonance through a 6V motor driving cams and spring actuators across four springs and two hanging masses on a 19-inch frame

Designed to teach Ohm's law and current-limiting behavior

lightweight and shatter-resistant for image-formation and ray-tracing experiments
