To investigate the relationship between the extension of a compact steel spring and the force producing that extension and to determine the elastic limit and force constant of the spring Apparatus Stand Spring 100g weights with hanger Clamps and Bosses A 1 meter ruler Set square Goggles Diagram Theory In 1676, Robert Hooke studied the strain on material. He found that the strain on the material is proportional to the stress producing it. This is shown as: Extension Stretching force Strain is the amount of change in size, which could be length, area or volume. The stress is the force divided by the surface area. When a spring is stretched, the force that is required to stretch it is proportional to the amount of extension. If a selection of springs were taken to stretch one spring twice a far as the other, twice the amount of force is needed. If three times the amount of force was used then it would produce...
