CYLINDERS SET EQUAL IN MASS -HLSI
A set of 6 metal copper, brass, aluminium, zinc, iron and lead of 100g ± 10% each and are drilled for suspension. A metal cylinder set consisting of six different materials: aluminum, copper, lead, tin, and zinc brass. Each are machined to an equal mass on a computer-controlled turning center and their metal is identified with a stamped symbol on one end. Since each specimen weighs the same and all are 1/2" diameter, this set is ideal for demonstrating reciprocal density and for computing the specific gravity of each element.
