Set of 3 Cylinders, Equal in Mass U8403325
Instruction sheet
11/07 ALF
1 Aluminium cylinder
2 Iron cylinder
3 Brass cylinder
1. Description
The set of three cylinders, equal in mass, is used for
determining the densities of different solid bodies.
The set consists of one cylinder each of aluminium,
iron and brass. Each cylinder is equipped with a
hook.
2. Technical data
Materials: Aluminium, iron, brass
Mass of cylinders: 100 g
3. Sample experiment
Determination of the densities of solid bodies
To determine the density the following equipment is
also required:
1 Electronic scales 600 g U42050-230
or
1 Electronic scales 600 g
U42050-115
1 Free Standing Cylinder U14206
• Place a cylinder on the scale and record the
weight.
• Fill the free standing glass cylinder with water.
• Suspend the cylinder from the hook of the scale.
• Immerse the cylinder completely in the water
and again record the weight.
As a result of the upthrust, the apparent weight of
the body is reduced by an amount equal to the
weight of the volume of liquid that it displaces.
• Note the difference in weight, and from that
calculate the volume of the cylinder.
• Calculate the density of the cylinder using the
equation
V
m
= ρ
.
• Repeat the measurements with the other cylin-
ders and compare the results.
