Equal Mass Set
Product Code : JA-MLE-9357
The Equal Mass Set (SKU JA-MLE-9357) is a set of five cylinders made of different materials that all have exactly the same mass, 15 g, and the same 1/2 inch diameter, but different lengths. With this equal mass cylinder set for density lessons, students see at a glance that the less dense the material, the longer the cylinder must be, because for equal mass and radius density is inversely proportional to length. The materials are brass, aluminium, nylon, PVC and polyethylene.
Specifications
The set contains five cylinders of brass, aluminium, nylon, PVC and polyethylene, each 1/2 inch in diameter and 15 g in mass, with lengths that differ according to density.

Teaching uses of the equal mass set
The set is used whenever mass, volume and density are taught, because holding equal masses of very different sizes makes the relationship between the three quantities obvious and gives numbers students can check.
- Showing that equal masses of different materials occupy different volumes
- Measuring the length of each cylinder and calculating its volume and density
- Demonstrating that, for equal mass and radius, density is inversely proportional to length
- Ranking brass, aluminium, nylon, PVC and polyethylene by density

Minimum order quantity, lead time and packing are confirmed on each quotation according to the number of sets and the delivery destination. JaincoLab supplies density teaching sets to schools, colleges and education projects, and exports to buyers in Africa, the Middle East and South and South-East Asia.
Frequently asked questions
What is the mass of each cylinder?
Each of the five cylinders has a mass of 15 g.
Which materials are included?
Brass, aluminium, nylon, PVC and polyethylene.
Why are the cylinders different lengths?
They have the same mass and the same 1/2 inch diameter, so a less dense material needs a longer cylinder; density is inversely proportional to length.
