Example 3: A composite spring has two close coiled helical springs connected in series; each spring has twelve coils at a mean diameter of 20 mm. Find the wire diameter in one if the other is 2 mm and the stiffness of the composite spring is 600 N/m. Estimate the greatest load can be carried out by the composite spring, and the corresponding extension, for a maximum shearing stress of 160 N/mm². Ġ = 75,000 N/mm
