- c) One of the bestselling items at the stall are gummy worms, so you decide to perfect the recipe. The ideal gummy will stretch a little as you bite into it, but not too much. The mold you use produces worms with a length of 0.1m and a diameter of 0.03m. You narrow it down to two recipes. In the graph below are the two possible options you produce when you hang weights from the bottom of your two most likely gummy worms and measure the extension. 8 6 Force (N) 0 0.2 0.4 Extension (cm) 0.6 0.8 Calculate the Young Modulus of the gummy worms by converting one of the options into a stress/ strain graph (to be shown with your answers) and the other by using calculations.
