Barton's Apparatus for Determination of Modulus of Rigidity (Statical Method)

The Barton's Apparatus for Determination of Modulus of Rigidity by Statical Method is a precision laboratory instrument developed for studying the torsional properties of metallic wires and accurately determining their modulus of rigidity. Manufactured by Micro Technologies, this apparatus is widely used in physics laboratories, engineering colleges, universities, polytechnic institutes, and scientific research laboratories.

The apparatus consists of a rigid steel frame mounted on a heavy-duty cast iron base fitted with levelling screws to provide excellent stability during experimentation. A 900 mm long and 5 mm diameter steel rod (test specimen) is securely clamped at the top using a precision three-jaw chuck, while the lower end is connected to a torsional drum arrangement.

The torsional drum rotates smoothly and transmits motion through low-friction pulleys, ensuring accurate application of torque with minimal mechanical losses. Freely sliding three circular graduated scales, calibrated in single-degree divisions, can be positioned anywhere along the apparatus for precise angular displacement measurements.

Three precision pointers are provided for accurate observation of angular twist during loading. The apparatus is supplied complete with three supporting rods, strings, and two scale pans for applying balanced loads during the experiment.

The instrument enables students to investigate the relationship between applied torque and angular deformation, allowing precise calculation of the modulus of rigidity of the test wire using the statical method.

The heavy-duty construction ensures excellent rigidity, minimizes vibration, and provides highly reliable experimental results. The apparatus is suitable for repeated laboratory demonstrations as well as advanced mechanics experiments.

Every Barton's Apparatus manufactured by Micro Technologies undergoes strict dimensional inspection and quality testing to ensure dependable performance, accurate measurements, and long service life.
