This isn't just another dry textbook And as for any structural engineering book or formula sheet, some explanations and formulas are simplified. 𝐶𝑃= 4𝜋2 𝑇2 𝑖𝑖. 000 001 10−6 micro μ 0. 1. This lecture note covers how to estimate the dynamic behavior of single degree of freedom (SDOF) systems and multi-degree of freedom (MDOF) systems. Natural frequency of a SDOF system in terms of the self-weight deflection > caused by 1g fn 1 2π g ∆ = i.
