Chain Drive with Tensioner Mechanical Demonstration Model Meters_Electrical Two-ohm wire-wound fixed resistor in

Two-ohm wire-wound fixed resistor in an ABS module with 4mm sockets

showing the deflection of a current-carrying wire through a fixed magnetic field via 4mm safety sockets

providing dense uniform spheres for ramp-and-collision experiments where a heavier projectile is needed than the plastic marbles can provide

5mm copper wire on a 5 x 4

and raised graduations with full autoclave and dishwasher tolerance

Chain Drive with Tensioner Mechanical Demonstration Model Meters_Electrical Two-ohm wire-wound fixed resistor inTensioner pulley keeps chain engagement consistent on this hand cranked chain drive, viewable between clear plates so students watch sprocket teeth grip and transfer torque under load.
