Short Description
Maxwell Vibration Needle
Graduated (Brass)
Country of origin: India
Specifications
- Brand: Reliant Lab
- Product Quantity : 1 Piece
Description
The Maxwell Vibration Needle consists of a hollow brass tube, typically 30cm to 40cm in length, which is suspended horizontally at its center by the test wire. The tube is designed to hold four identical cylinders two solid and two hollow which are of the same length and diameter. The "graduated" version features a scale along the length of the tube to ensure the precise symmetrical placement of these masses. The Modulus of Rigidity of the suspension wire can be calculated without needing to know the mass or dimensions of the needle itself, effectively eliminating several sources of experimental error.
Features
:- Graduated Brass Tube: The main hollow member features an engraved metric scale to allow for the highly accurate, symmetrical positioning of internal masses.
- Torsional Suspension Chuck: Equipped with a high-quality split chuck at the center of the needle to grip the test wire firmly and prevent slipping.
- Error Eliminating Design: The "Maxwell Method" mathematically removes the need to calculate the moment of inertia of the needle frame, focusing purely on the mass shift.
- Mirror Attachment: Includes a small plane mirror fixed to the center of the needle for use with a lamp and scale arrangement to track oscillations.
Applications
:- Moment of Inertia Studies: Demonstrating how the distribution of mass relative to the axis of rotation changes the period of vibration.
- Comparative Material Science: Investigating how different wire diameters and material compositions affect the torsional constant.
- Dynamic Measurement Training: Teaching students how to use the "difference of squares" of time periods to simplify complex physical equations.
- Advanced Mechanics Labs: A core experiment for senior undergraduate physics and mechanical engineering students to understand rotational SHM.
