RAWPIE PROBLEM 18.2 thelical compression spring should apply a force of 1000 N when it is compressed by 10 mm . the outside space available for the spring is 37 mm and it is to be fitted over a rod of 19 mm dimeter. There should be a clearance of 1 mm at inner and outer diameters of the spring. The faximum deflection of the spring is 12.5 mm . Design the spring using static load approach. Use a factor of safety of 2.5 .
