This could have been because the clamps were no tightened at the same strength.

The same rule will be used throughout the experiment, so that mass and width etc. will remain constant. 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.

I could have improved my procedure for this experiment by using more accurate equipment such as right angle triangle rulers. I could have also varied the force of the weight bit more to see if the ruler reached a point where it would stop depressing and stay the same position, this is especially true for the plastic material and it snapped when 1 extra weight was added, if I used less heavier weights I could have seen the elastic limit in more detail and drawn graphs and conclusions based on them. This wooden ruler will be a fantastic addition to your sewing kit, and will even prove useful for other general tasks. You'll be able to ensure absolute precision with this handy measuring tool! When the distance between the supports increased the sag also increased, but not in a proportional way, just like in the wood. The reason it curved was just like the reason the wood curved, this was because the bonds were reaching its elastic limit. For my second rough experiment I did the compound pendulum experiment. I set up the experiment which is shown under the heading ‘rough trials apparatus 2’. I first put a rule on the side of a table. This was used to measure the distance the swinging rule was held out at, (0.2 meters). I then got another rule which had three holes drilled into it (at the points 0.05 meter, 0.1 meter and 0.15 meters). Then I attached a clamp to a stand. Using a nail small enough to fit through the drilled holes I put it through the first hole and attached the end of the nail to the clamp holding the stand. I put the clamps holding the rule which could then swing at the middle point of the horizontal rule (0.5 meters). The stand was placed at the edge of the table so that the meter rule was allowed to swing. My graphs showed me a good set of results. My graph had a straight line of best fit which represented the results gained. The graph had a straight line travelling diagonally upwards towards the right, this is because as the force of the weight increased the depression of the ruler also increased, and this is due to Hooke’s law. I drew a curved line of best fit for when the force used way 9.8N; this was because of elastic limit which is explained in analysis. There were some irregular results gained from some of my graph, but they were not seriously out of line from the best fit. These could have occurred from a number of errors:After ten weights are applies and the level of deflection are taken I will change the length variable by moving the tables so that 0.1 meters of the rule will be covered and then redo the measurements. I shall decrease the length of the ruler by 0.05 meters each time about five times.

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. I will make sure the horizontal ruler is straight and not bent as this would cause readings to be read incorrectly. I could have tested shorter lengths, this would have allowed me to really see if the pendulum and sag has any similarities when the length was constant. Friction between the hole and the nail as well as the table and the rule. Sometimes the rule swung diagonally and might have rubbed the table.To make sure that I do not move when I am taking the readings so that I get the correct results as much as possible.
