Mechanical equivalent of heat: Aluminum cylinder, crank, rope with 5 kg weight and large LED display.

Mechanical equivalent of heat: A nylon rope is wrapped around an aluminum cylinder multiple times. The rope supports a 5 Kg. mass. When the handle is turned repeatedly, the rope slips smoothly on the cylinder, heating the cylinder. The temperature rise of the cylinder is sensed by a thermistor and shown on a large display.
