Whirlybird Essay Example For Students

Whirlybird Essay Yr 11 MATHS B ASSIGNMENTTask oneThe aim of this assignment was to determine and create the most suitableand efficient Whirlybird which could sustain flight times the longest. Themethod followed to achieve this was a series of flight test. Differentsizes of Whirly birds were created in 2cm intervals in the length and thewidth. Then each model will be dropped from the same height keeping allvariables the same, six times and recording the flight time to the ground. The recorded flight times will be analysed and used to determine the bestWhirlybird. It will be analysed using different mathematical methods andgraphs to provide suggestions. The process taken to complete the experimentfollowed the method explicitly. The recording of the whirlybird drops wereunaffected by natural elements such as the weather because it was keptindoor in a controlled environment (wind resistance and hight control werenot a problem). The timing using a stop watch was kept by the same personso reaction time would not defer while recording. When transferring thedata to a computer for analysis, the means and standard deviation werecalculated for each of the six drops of each whirlybird and put into datalplots. The data plots were used to break down the information and put intoTI Interactive. It would then use it aid in the analysis process byplotting graphs and calculating a regression.

It consists of the six drops for each whirly bird and the mean and standarddeviation of each set. The Mean and standard deviation were calculated toeasily identify the best length for a whirlybird. The data marked in REDwere selected as the out riders they were taken out of the calculation toensure the results were ordinary and not unique for the information. Task 3The data below is the graphical representation of the results recordedduring the flight test for the best length of a whirly bird. TI Interactivewas used because of it ability to produced the most accurate and reliableresults for finding the quadratic regression and line of best fit for thegraph. The graph bellow was chosen because it depicts the movements of thedata accurately along the graph. picpicpic(9.16379, 4.55496) MaximumTask 4A separate investigation was set up to the determine the best width for thewhirlybirds wings. It followed the same process and method as the firstexperiment. Except for the fact that the width length would only be betweenone and three cm. It had the same six drops for each of the threewhirlybirds and was recorded under the same conditions as the firstexperiment, it was then recorded and the same calculations were made beforetransferring the data onto a computer. It was then analysed and thefollowing were created using TI Interactive quadratic regression, agraphical display and data table.
