A light wooden uniform metre rule was clamped to the surface of a bench so that a length L of the metre rule was hanging over the edge. The overhanging end of the metre rule was loaded with a mass and the depression D produced at the loaded end was measured. Values of D were obtained for different lengths L. L (mm) D (mm) 200 2.0 300 6.0 400 13.0 500 28.0 600 49.0 700 75.0 800 109.0 Assume that D = KL", where K and n are constants, and draw a graph that would enable you to determine the values of n and K. Use a linear regression analysis of the data to fit the best straight line through the data and determine the value of D for L = 100 mm from the graph.

Hi,
Please pay attention to what the question is asking. It clearly states to draw a graph and to fit the best straight like through the data.
Thanks in advance

Assume that D = KL", where K and n are constants, and draw a graph that
would enable you to determine the values of n and K. Use a linear regression
analysis of the data to fit the best straight line through the data and determine
the value of D for L = 100 mm from the graph.
