Investigation in to the bending Of material in the form of A beam.

Extracts from this document...

Introduction

Investigation in to the bending Of material in the form of A beam In this experiment we wanted to investigate how far a beam would bend when weights were attached to the end. We put a 1m ruler on the end of a desk and then added weights to the end of the ruler; the weights went from 100g to 800g. The height of the ruler off the ground was 82cm. There are many variables you can change for this investigation, such as: The length of the ruler, the length of the ruler off the desk, the height above ground and the mass on the ruler. We changed the mass put on the ruler. Prediction My prediction for this experiment is that the more weight added to the ruler, the more the ruler would bend. ...read more.

Fair Test To make this experiment a fair test, we have to: * Keep the ruler at the same length after each weight has been placed on. * Keep the ruler at the same height so it does not change the bendiness of the ruler. * Add 1 weight at a time * Always measure the bend of the ruler at a certain time after the ruler has stopped bouncing, so you do not get a wrong measurement. ...read more.

Conclusion

This can also mean that1 weight can be � to 1cm off bending. These results do match my prediction because the more force added to an object the more the object will have to bend/move etc. Evaluation I think the experiment went well, because our results were all accurate and in a graph all went together well in the line of best fit. The graph does show a very good line of best fit. Most off the results in the graph are not anomalous, however the results are not exact and a few are a little bit under or over the line of best fit. The results are quite accurate, but you would not be able to tell the difference of decimal points. We could improve this investigation by choosing a different variable, which would have been a little harder to work out answers. Lauren Ardolino 9CW ...read more.

    This in turn prevents the airflow from reaching supersonic speeds until a much higher TAS is reached, thus raising the MCRIT number.

    This is because I am only investigating this experiment with varying weight. (100mm) * The length of the bridge (900mm) Experiment B * The position of the weight must be in the same position. If it weren't it would mean that the moments on each side would be different.
