Product Description

Mechanical Equivalent of Heat

This Apparatus provides an update version of one of the Joules most important experiments, converting mechanical work into thermal energy and determination of the relationship between mechanical work done and units of heat energy. It includes a base, cylinder, crank and counter with a built-in table clamp, 2.5 meters of nylon rope, 5kg of laboratory masses. Complete with instruction manual.

Features:

          Easy to use with Accuracy of 5%.

          Rugged Ball Bearing Construction.

          Thermoelectric probe Directly give temperature readings. No Thermometers to Break.

          Double Ball Bearings - Minimize the wear of moving parts and enhances the life of apparatus.

          Counter: Counts and displays the number of rotations. One cannot forget how many times he has cranked.

How It Works: A nylon rope is wrapped several times around the aluminium cylinder. Rotation of the crank performs a measurable amount of work. This in turn, rotates the cylinder. With the rotation of the crank, the friction between the rope and the aluminium cylinder is just enough to support a mass hanging at the other end of the rope ensuring that the torque acting on the cylinder is constant and measurable. A counter keeps track of the number of rotations. The work done in rotating the cylinder is converted into thermal energy due to the friction between the cylinder and the rope. This results in rise in the temperature of the cylinder, which can be noted by using the thermoelectric probe & digital multimeter. The ratio between the work done and the thermal energy produced and transmitted to the cylinder determines J, the mechanical equivalent of heat. With this apparatus, the value of J can be determined to an accuracy of within 5%.
