Product Information This apparatus is easy to use, reliable and provides accurate results to better than 5%. Wind the nylon band several times around the aluminum cylinder and hang a large weight such as a can of sand on one end. When the crank is turned to raise the weight, frictional heat is created by slippage of the cord. Students calculate the work done and read the temperature change to find the heat produced. A calibration chart is provided to convert thermistor voltage to temperature. Features rugged, ball-bearing construction, industrial grade revolution counter, build-in friction pad and guides for the friction rope for an easier initial set-up. Comes with can for holding mass, tube of dry graphite and instructions.  Tell a Friend about this item
