Cantilever Deflection.

Extracts from this document...


Cantilever Deflection Preliminary Work The more weight there is on the ruler, The more deflection there is. Prediction I predict, that as the mass increases, the deflection of the ruler will increase. I think this because, the more mass on the ruler, will result to more weight, therefore there would be a larger force acting down on the ruler, causing an unbalanced moment, which will cause the ruler to deflect. Due to my preliminary results, I have realised t hat, if I double the mass on the ruler, the ruler will almost double in deflection. Therefore, if I were to plot a graph from my results, I would find that I would get a straight-line graph going through the origin, as the ruler deflects in proportion. ...read more.


1. Where I'm going to place the masses on to the ruler. 2. How I decide to place the ruler. 3. Where I decide to have the pivot. * I am going to control the masses that I shall place on to the ruler. * I am going to measure the deflection of the ruler, when various masses are placed on to it. Diagram Method I will set up the apparatus, as shown. Then I will test it with masses on it over the range, that I describe in my variables. Results Mass/Kg Height of ruler after masses/cm Deflection of the ruler/mm 0.1 84.5 5 0.2 84.0 10 0.3 83.5 15 0.4 83.0 20 0.5 82.5 25 0.6 82.0 30 0.7 81.5 35 0.8 81.0 40 0.9 80.5 45 1.0 80.0 50 Analysis The graph shows that the mass on the ruler had an effect on the deflection of the ruler. ...read more.


As I was aware of this scientific knowledge, it was obvious, that increasing the mass on the ruler would increase the deflection of the ruler. Evaluation The experiment, gave very reliable results. This is because the results lied very close to the trend line on the graph. The reasons for this might include: * There was only one person taking the measurements. * The same ruler was used throughout the experiment. * The masses were placed in a fixed position during the experiment. * The pivot was in a fixed position during the experiment. * The ruler was on its side throughout the experiment. * A suitable range of masses were used for the experiment.

After passing through the flexible production process each individual product must reach to the right person. Also, as the production stages may be in different places, the passage of the semi-finished products within the process should be fool proof.
