Copper and Iron Compound Bar for Thermal Expansion Heat & Thermodynamics_Temperature & Heat letting students see conduction-rate differences

letting students see conduction-rate differences in one view

and a pulley for introducing momentum

with AC and DC both available on separate terminals for electronics builds

Large-wheel pulley mounted on a universal clamp for attachment to retort rods or support stands

sized for resistance coils and thermocouple legs where copper-nickel alloy holds its value across temperature swings

Copper and Iron Compound Bar for Thermal Expansion Heat & Thermodynamics_Temperature & Heat letting students see conduction-rate differencesRiveted compound bar of copper and iron strips at 200 by 15mm, flexing under heat as each metal expands at a different rate, the working principle behind bimetallic thermostats.
