Creep Testing Machine Lab

This simple machine uses specimens of lead and different plastics which
creep significantly at room temperature and under low loads.
Its main part is a simple lever (load beam) with a mechanical advantage
of 8:1.
The load beam gives a steady and uniform tensile load.
A digital indicator measures the extension (creep) of the specimen under
load.
For effect-of-temperature tests, the student freezes or heats a
cool-pack and places it next to the specimen.
To ensure correct loading of the specimen, the load beam has a
ball-bearing pivot.
To apply a load, students add weights to a weight hanger and measure
time and the creep.
They then fit the transparent enclosure to preserve the temperature
around the specimen during the test.
