5 Apparatus and materials

5.1 Apparatus

5.1.1 A pulling device, able to pull a loaded slider assembly at a constant speed, to a tolerance of 0,01 m/s,

within the range of 0,20 m/s to 0,30 m/s along a length which allows a stable measurement reading for at least

0,30 m.

5.1.2 A measuring device, capable of measuring the horizontal force with an error limit of 1 %.

5.1.3 A slider assembly, with two leather sliders and one shoe rubber slider of shape and dimensions specified

in Figure 1, arranged on the assembly as shown in Figure 2. The three sliders shall be of similar thickness within

the range 2 mm to 6 mm, to ensure that they are all capable of being in contact with a flat surface, and shall be

firmly fixed to the assembly by means of a contact adhesive. The slider assembly shall be loaded with a mass such

that the total mass of the loaded slider assembly is (10,0 ± 0,1) kg.
