Clearly,this is an important consideration in the design of a connector spring.The elastic modulus of steel alloys ranges from 16 to 20 million pounds per square inch (about 110 to 138 kMpa).This range is representative of practically all of the steel alloys used for connector springs. results for this questionFeedbackElastic Modulus of Spring Design - Ace Wire SpringModulus of Eslasticity.The modulus of elasticity in tension and shear is vital to spring design.For most steels and age- hardenable alloys,the modulus varies as a function of chemical composition,cold work and degree of aging.Usually variations are small and can be compensated for by adjustment of reference parameters of the custom spring design,(e.g.number of active coils,and coil diameter). results for this questionHow do you find the elastic modulus of a spring?How do you find the elastic modulus of a spring?To actually find the Then we just need to measure how much additional strain is caused by an applied stress (or vice versa) then divide the stress by strain to get the elastic modulus.Of course we need to be sure that the material is operating within its linear region,so that it still acts like a spring.Elasticity of the Body Body Physics Motion to Metabolism
