Equal Mass Set
Model Number: MTM-34
The Equal Mass Set from Micro Technologies is designed to demonstrate the inverse relationship between material density and specimen length when mass and cross-sectional area are kept constant. The set contains equal-mass specimens of aluminium, copper, nylon, PVC and polyethylene, each with an approximate diameter of 12 mm, while specimen lengths vary from approximately 15 to 100 mm. Instructions are included.
Product Specification
The Equal Mass Set from Micro Technologies is an educational physics and material science apparatus designed for comparative experiments involving mass, density, volume and length. The set provides a clear physical demonstration of how materials with the same mass can occupy different volumes because of differences in density.
The complete set contains specimens made from aluminium, copper, nylon, PVC and polyethylene. These materials represent both metals and polymers, providing a broad range of densities for comparison.
Each specimen has an equal mass, making mass a controlled quantity during the experiment. This allows differences in specimen dimensions to be related directly to differences in material density.
The specimens have an approximate diameter of 12 mm, providing a comparable cross-sectional area. Their lengths vary substantially, ranging from approximately 15 mm to 100 mm.
For cylindrical specimens of equal diameter and equal mass, a material with a higher density requires a smaller volume and therefore a shorter specimen length. A lower-density material requires a greater volume and consequently a longer specimen.
This makes the set particularly effective for demonstrating the inverse relationship between density and length under equal-mass and equal-cross-section conditions.
The copper specimen provides an example of a relatively high-density material and therefore requires comparatively less volume for the same mass. Lower-density polymer specimens occupy a greater volume and are correspondingly longer.
Students can visually compare the specimens before carrying out mathematical calculations, making an otherwise abstract density relationship easier to understand.
The apparatus can also be used to reinforce the standard density relationship:
Density = Mass ÷ Volume
Since the specimens are cylindrical, their volumes can be calculated from measured diameter and length. Students can use a suitable Vernier Caliper or other measuring instrument to obtain dimensions for quantitative analysis.
The set can further support comparisons between metals and polymers, helping students understand how material selection influences mass, dimensions and volume in practical engineering applications.
Students may arrange the specimens according to length and predict their relative densities before comparing their observations with known material properties.
A suitable laboratory balance can also be used to verify that the specimens have approximately equal masses, providing an additional measurement activity.
The wide length range of approximately 15–100 mm makes the difference between materials visually apparent and useful for instructor-led demonstrations as well as student practical work.
Instructions are supplied with the set to support appropriate educational use and experimental activities.
Manufactured and supplied by Micro Technologies, the Equal Mass Set is suitable for physics laboratories, material science laboratories and educational institutions studying density and physical properties of materials.

FAQs
What is an Equal Mass Set used for?
The Equal Mass Set is primarily used to demonstrate the inverse relationship between density and specimen length when the specimens have equal mass and approximately equal diameter.
Which materials are included in the set?
The set contains specimens of aluminium, copper, nylon, PVC and polyethylene.
Do all specimens have the same mass?
Yes. The specimens are designed to have equal mass, while their lengths differ according to material density.
What is the diameter of the specimens?
Each specimen has an approximate diameter of 12 mm.
What is the length range of the specimens?
The specimens range from approximately 15 mm to 100 mm in length.
Why do equal-mass specimens have different lengths?
Different materials have different densities. With equal mass and comparable cross-sectional area, a higher-density material requires less volume and therefore a shorter length, while a lower-density material requires greater volume.
Which types of materials are represented?
The set includes two metals—aluminium and copper—and three polymers—nylon, PVC and polyethylene.
Can students calculate the volume of the specimens?
Yes. Since the specimens are cylindrical, their volumes can be calculated using measured diameter and length.
Are instructions included?
Yes. Instructions are supplied with the Equal Mass Set.
Where can the Equal Mass Set be used?
It is suitable for physics laboratories, material science laboratories, schools, colleges, universities and educational science facilities.
