  • Downloads and Documents


In this experiment, a metal test body is rotated and heated by the friction due to a tensed band of synthetic material.The mechanical equivalent of heat for problem 1 is determined from the defined mechanical work and from the thermal energy increase deduced from the increase of temperature. Assuming the equivalence of mechanical work and heat, the specific thermal capacity of aluminium and brass is determined.


  • Elegant set-up to measure conversion of mechanical energy in thermal energy
  • Perfect as demonstration experiment and very suitable as an introductory student experiment


  1. Determination of the mechanical equivalent of heat.
  2. Determination of the specific thermal capacity of aluminum and brass.
