Cure fraction models on survival data and covariates with a Bayesian parametric estimation methods
Abstract
Several researchers have carried out derivation of equation of motion of mechanical systems
with more than one degrees of freedom of movement using different approaches among which is
the work of Sivak and Darina [11] who derived the equation of motion of a translational
mechanical system with two degrees of freedom using Newton’s second law. This paper,
therefore, provides an extension of the work of Sivak and Darina [11] to model a three degree of
freedom translational mechanical system. The free-body diagrams of the individual masses are
developed and then Newton’s second law applied. Finally, the three equations derived are
presented in matrix form in order to solve the system vibration problems
