! Required information A helical compression spring is made of hard-drawn spring steel wire of diameter 0.0773in. and has an outside diameter of 0.85 in. The ends are plain and ground, and there are 8 coils. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. The spring is wound to a free length, which is the largest possible with a solid-safe property. Find this free length. Assume a design factor for solid-safe loading of ns = 1.2. The free length is Tin.
In a compound helical spring, the inner spring is concentric with the outer spring, but is 9 mm shorter. The outer spring has ten coils of mean diameter 24 mm, and the wire diameter is 3 mm. Find the stiffness of the inner spring if an axial load of 150 N causes the outer spring to compress 18 mm. If the mean coil diameter for the inner spring is 15.94 mm, find the wire diameter of the inner spring when it has eight coils. Both the springs are made of the same material having G = 77 GPa.
