Linear Expansion Simple Form

Linear Expansion Simple Form

Linear Expansion Simple Form

Categories: ,

Model No: AGN-2611
The Linear Expansion Apparatus in simple form is designed to study the bending of a bimetallic strip or thermal expansion of a single metal rod (brass) when heated. Its simple yet rugged construction makes it ideal for elementary physics experiments in schools and colleges. The apparatus allows students to observe and measure the expansion of a brass rod as it is heated, providing a clear demonstration of the principles of linear thermal expansion.

Technical Specifications

  • Sturdy Base: Heavy metallic base measuring 50 × 10 cm, providing stability during experiments.
  • Four Vertical Pillars:
    1. Pointer Pillar: Supports a pointer pivoted at its upper end; the free lower end moves across arbitrary scales. Also includes a supporting bracket for the specimen rod.
    2. Scale Pillar: Carries the arbitrary measurement scales for reading expansion.
    3. Central Pillar: Holds the brass rod at the center.
    4. Adjustment Pillar: Supports the second end of the specimen rod and features a screw for setting the pointer to zero.
  • Specimen Rod: Brass rod of 12.5 × 5/32 inches suitable for thermal expansion studies.
  • Heating Method: Rod can be heated using a spirit burner or candle to demonstrate thermal expansion.
  • Simple and Economical: Compact design makes it widely used for basic physics experiments and classroom demonstrations.
