Center of Mass Roller-and-Ramp Demonstrator, 17" Microscopy_Microscopy Equipment &Supplies Sturdy wooden pulley simple-machine model

Sturdy wooden pulley simple-machine model with multiple pulleys mounted in series and parallel

designed to receive real images projected by lenses and concave mirrors during focal-length and magnification experiments on the optical bench

allowing this tangent galvanometer to convert deflection angle into an absolute current reading

and vascular tissue at greatly magnified scale
