This function allows users to design a new rod taper or modify the existing rod taper by drawing a Stress Curve. It was difficult to specify a Stress Curve manually. Especially it was the problem how to specify the small difference of Stress over the rod. If it became true, we could establish a new method to define the target rod by drawing a Stress Curve. DynaRod made it possible as its sub tool, "Stress Curve Drawer" which works on Excel workbook. DynaRod and "Stress Curve Drawer" now coworks. "Stress Curve Drawer" will define the target stress curve which is deflected. DynaRod receives the stress distribution and calculate the dimension for the stress distribution. DynaRod defines the word "Stress Curve" as follows; In Garrison math, the stress curve is the plot of the number, the moment value divided by the section modulus, at each point over the rod. This can also be said as "the plot of the stress values BEFORE the rod is deflected". On the other hand, DynaRod's stress curve is the plot of the number, the moment value which is calculated reflecting the rod bend at the continuous point of time, divided by the section modulus, at each point over the rod. This can also be said as "the plot of the stress values AFTER the rod is deflected". User should be familiar with that the rod movement assumption, "Translated Rod", is used in the calculation of this function. To design a completely new taper As this program is so designed to start with a template rod in order to prepare the starting dimensions of a rod, user must select an existing rod as a template. Then how to design a rod taper "from scratch"? It is WHEN changing the deflection via changing the Stress graph on "Stress Curve Drawer" tool. Just neglect the existing Stress Curve of template and newly define the Stress line on the tool. [Design by Stress Curve] program in DynaRod receives the newly defined Stress data and calculate the newly designed dimensions as a completely new taper. Data on screen
