Question
A 50 kg dough machine is mounted on an elastic support and opera to a speed of 1000 rpm. It has an unbalanced mass of 2 kg at an eccentric distance of 0.1 meter. If the damping factor ℶ = 0.2, determine: a) the constant of the support spring (without damping) which only transmits only up to 28% of the unbalanced force to the foundation, b) the resonant frequency in rpm, and c) the magnitude of the force transmitted with the complete suspension d) Illustrate using graphics
