I am doing an investigation in to how much a metre rule bends when one end is clamped to a table and a varied load is attached to the other end that hangs off the table, thus bending the rule.

Physics Sc1 The Plan: Simple procedure: I am doing an investigation in to how much a metre rule bends when one end is clamped to a table and a varied load is attached to the other end that hangs off the table, thus bending the rule. I shall take relevant readings that I shall repeat three times and record the results in a table. Hypothesis: I hypothesise that the greater the load attached to the metre rule, the more the metre rule will be inclined to bend. There are two reasons for this. The first is because 'the extension is directly proportional to the stretching force.' This is Hooke's Law but cannot only be applied to springs, but also to metal wires, girders in bridges, but more importantly anything where the extension will be affected by the load. To see if my prediction is correct I will experiment, and obtain results using Hooke's Law....
