A compression spring has 20 coils with squared and ground ends, a free length of 1.25 in. and an outside diameter of 0.281 in. It is made of music wire with a diameter of .035 in. What is the spring rate (k) of the spring? What is the stress in the spring if compressed to solid height?
A helical compression srping is to be made of oil-tempered wire of 4 mm diameter with a spring index of C = 10. The spring is to operate inside a hole, so buckling is not a problem and the ends can be left plain. The free length of the spring should be 80 mm. A force of 50 N should deflect the spring 15 mm. Su = 1750 Mpa, allow for a 10% clash allowance and G = 79 GPa....
