The distance the rule was moved to be ready for the swing was 0.2 meters. This could have not been accurate for each experiment as I had moved and so the position may seem the same but in fact be different.

I think the procedure I used was quite suitable for this experiment. I varied the force of the weight greatly from 0.98N to 9.8N which gave me reasonable results which I could draw conclusions with. I could have repeated the experiment several times and drawn an average; this would have helped me get more accurate results. I think my investigation went pretty well. I am very pleased with the results I gained because they had shown me a good trend/pattern which I could refer to.

This will definitely affect my final results. The bonds in the wooden rule started to reach their elastic limit at about 0.75m, the bonds in the metal rule some of the bonds started to there elastic limit at about 0.70M. The sag at the point when the elastic limit was reached for the metal rule was about 0.01m, whereas the sag point when the elastic limit was reached for the wooden rule was about 0.0015. This shows that the wooden rule has a lower elastic limit compared to the metal one. ruler for boys,1st class ruler,custom ruler,engraved ruler,personalised Wood Ruler,centimeter ruler,School ruler,math ruler,initial on ruler Based on my graph where only 0.98N were attached to the centre of the rule, as the length increased the sag also increased and it produced a straight line which proved that the reason it curved when more weights were added was due to its elastic limit.

X2 on the graph is the point from the nail to the centre of the rule which is the length of the rule. Elastic limit as measured in tests and used in design may be defined as that unit stress at which the deformation begins to increase in a faster ratio than the applied load. In practice the elastic limit of a material under test is determined from the stress-strain diagram. It is that point in the line where the diagram begins perceptibly to curve.

When external forces act upon a beam in a direction away from its ends or a direct pull, the stress is a tensile stress. The strain is an increasing.
