Reliant Lab Young’s Modulus Appratus (Searle’s Pattern), Iron

• Number of Brass Frame : 2
• Micrometer Head Reading : 1/100 mm

Features

• Dual Frame Compensation: Comprises two identical iron frames to support a reference wire and an experimental wire, automatically neutralizing errors from temperature expansion.
• Precision Micrometer Screw: Equipped with a high-accuracy micrometer to measure microscopic longitudinal extensions.
• Highly Sensitive Spirit Level: Features a spirit level pivoted at one end and resting on the micrometer tip at the other to ensure precise horizontal alignment.
• Robust Iron Construction: The main frames are cast from heavy duty iron, providing the rigidity necessary to maintain alignment under significant tension.

Applications

• Material Science Education: Serves as a fundamental experiment in engineering and physics curricula to understand the mechanical properties of solids.
• Wire Testing: Used to compare the elasticity of different materials like iron, brass, copper, or steel under controlled laboratory conditions.
• Verification of Hooke’s Law: Experimentally confirms that within the elastic limit, the extension of a wire is directly proportional to the applied load.
• Precision Measurement Training: Helps students develop skills in using micrometers and spirit levels to perform high precision physical measurements.
