Young Modulus Apparatus Searle Type

Young’s Modulus Apparatus – Searle Type

The Searle’s Apparatus for Young’s Modulus is a high-precision educational and experimental tool designed for determining the Young’s Modulus (modulus of elasticity) of metallic wires. Commonly used in physics and material science laboratories, this device allows students and researchers to explore fundamental principles of elasticity with exceptional accuracy.

Built with precision engineering, this apparatus includes two identical metallic wires—one acting as the control and the other as the test sample—secured to a robust frame. When a known load is applied, the resulting extension in the test wire can be compared against the control using a sensitive spirit level and a finely calibrated micrometer screw gauge. This setup ensures minimal error and delivers highly reliable results, making it an essential teaching aid in advanced secondary and university-level labs.

Key Features:

• Robust Construction: Corrosion-resistant materials ensure longevity and consistent performance.

• Twin-Wire Design: Minimizes error by using a reference wire for comparative analysis.

• High Sensitivity: Spirit level and micrometer screw enable fine detection of elongation.

• User-Friendly: Simple assembly and straightforward operation make it ideal for students.

Applications:

• Ideal for verifying Hooke’s Law and stress-strain relationships.

• Suitable for undergraduate laboratory practicals and experimental physics coursework.

• Frequently used in quality control testing for metal wire properties.

Package Includes:

• Sturdy metal frame

• Two identical wires (usually steel or copper)

• Load hanger and precision weights

• Micrometer screw with calibration

• Instruction manual with experiment guidance

With its durable design and accurate measurements, the Searle’s Apparatus is an indispensable tool for any lab studying material behavior under tensile stress.
