A helical compressionspring is to exert a force of 36 N when compressed to alength of45 mm.Further compressed to a length of 31 mm, the force must be 54 N.Thespring will be installed in a machine that cycles slowly,and approximately 200 000totalcycles are expected.Tempretaureis not expected to exceed 80 °C. It is planned to install thespring in a hole having a diameter of 19 mm. Use ASTM A23X series steel wire.For this application, specify wire diameter, mean diameter,outer diameter, innerdiameter, free length, solid length, number of coils and type of end condition.
