Once some weights were added the set up looked unstable and dangerous as the rule started to twist. This could have been because the clamps were no tightened at the same strength.

This problem could be fixed if the rule wasn’t held down but rather on top of two equally level object.

In my first experiment I aim to find out how weight and length affect sag. I will only change one variable at a time. I shall do this by setting up an experiment as seen on the apparatus diagram 1.

Air resistance: It is assumed that there is no air resistance and 100% of gravitational potential energy is converted to kinetic energy, and vice versa. If successively larger loads are applied to a body and then removed it will be found that at first the body completely regains its original form upon release from the stress--in other words, the body is ~elastic~. Eventually a point will be reached where the recovery of the specimen is incomplete. This point is known as the ~elastic limit~, which may be defined as the limit beyond which it is impossible to carry the distortion of a body without producing a permanent alteration in shape. After this limit has been exceeded, the size and shape of the specimen after removal of the load will not be the same as before, and the difference or amount of change is known as the ~permanent set~. Once the weights were added, the level of deflection appeared to be different. This was probably because I had to get up to get the weights and the position of myself and the vertical rule change. This could result in inaccurate results.

I will not move when I am placing the weights on the rule and recording my results. I shall do this by keeping the weights near. Personalised Wooden Ruler, Cherry 30cm or 12 inches wood ruler, laser engraved any text or font. Name engraved school, logo or image Natural I will stay at the same point to complete this experiment and record results. This should mean that the position in which I let go of the rule will be similar throughout the whole experiment. Size of the displacement: This was 0.2m. Each measurement has an absolute error of ±0.5 centimetre as each measurement is given to the nearest centimetre.

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. 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.
