The spring characteristics therefore depend on the shear modulus, not Young's Modulus. PAN has properties involving low density, thermal stability, high strength and modulus of elasticity. The inverse of the bulk modulus gives a substance's compressibility. The modulus of elasticity may often be considered constant. Intrinsic is the expectation for positive bulk modulus and positive density. Its estimated shear modulus is similar to that of lead. The effect of plasticizers on elastic modulus is dependent on both temperature and plasticizer concentration. The speed is determined by the water's bulk modulus and mass density. The results showed that both hydrogels have a similar elastic modulus. The speed is determined by the water's bulk modulus, mass, and density. This requires negativity in bulk modulus and density. Modular exponentiation is a type of exponentiation performed over a modulus. It can be converted into viscous longitudinal modulus. Wider number systems exist which have a multiplicative modulus (e.g. 16-dimensional conic sedenions). Thin lines show intermediate levels of constant modulus and constant phase.
