Q.3 A counter-rotating eccentric mass exciter consisting of two rotating 400 g masses describing circles of 150 mm radius at the same speed, but in opposite senses, is placed on a machine element to induce a steady-state vibration. During a free vibration test, the assembly is displaced and released, the period of vibration is t s, and the ratio of consecutive amplitudes is r to 1.0. The spring stiffness is k = 550 N/m. When the speed of the exciter is 1200 rpm, determine: a) the amplitude of vibration b) the transmitted force to the ground exciter machine k 2 ||

A wheel is free to rotate about its fixed axle. A spring is attached to one of its spokes at distance r from the axle. Assuming that the wheel is a hoop of mass m and radius R, what is the angular frequency w of small oscillations of this system in terms of m, R, r, and the srping constant k? What is w if r =R and if r = 0? Thank you for the help. I think I'm tripping myself up with using r in the equations.
