Looking for spring rates for NBR rubber
hardness - 75 shore a
tensile - 2000 psi
100% modulus - 980 psi
for Neoprene
hardness - 75 shore a
tensile - 2710 psi
100% modulus - 650 psi
ultimate goal is to find how much it deflects under a certain load ( rubber thickness .125")
What is the torsional strength of a 316 stainless steel bar round. say for example 5.00 diameter. Do we use yield strength or ultimate for shear stress for this equation. Thanks.
