1. Linear Trendlines (See this link for trendline help): Using the data set given in Excel Supplement Part 1, we want to show that the beam deflection, given in millimeters, is linearly dependent on the load, given in Newtons. This means deflection will be plotted as a function of load. In other words, the deflection will be measured along the y-axis and the load will be measured along the x-axis. a. Add a linear curve fit of the plotted data with the line going through the origin by adding a linear Trendline element to your chart and setting the intercept of that line to zero (i.e., make sure "Set Intercept" is selected and equal to 0). b. Display the linear trendline equation on the chart (i.e., “Display Equation on chart" is selected). Display the equation's slope to 3 decimal places (select Category: Number and Decimal places: 3). c. Make sure your chart's axes and title are appropriately labeled. Include units with your axis labels. Do not display a legend. For the Chart title,…
