The following data refer to two close-coiled helical steel springs.
One spring is placed inside the other, not touching each other, and compressed between a pair of parallel plates until the distance between the plates is 40 mm. Make a neat detailed sketch of the spring and plate assembly. If G = 83 GPa for both springs, calculate the following:
5.1 The force applied to the spring assembly. /4/
5.2 The shear stress induced in each spring./3/
5.3 The total strain energy stored in the spring assembly./3/
5.4 The stiffness of each spring./3/
5.5The equivalent stiffness of a single spring that can be substituted in place of these springs.
