A machine (weight mg = 3000 N) is installed on a flexible base. The static deflection of thebase due to the weight of the machine is 7.5 cm. Measurements revealed that the machinevibrates at resonance with an amplitude of 1 cm when the base vibration amplitude is 0.25 cm.Determine the damping coefficient c of the base. Consider the resonant condition. Kone (mg = 3000 N) on asennettu joustavalle alustalle. Alustan staattinen painuma koneenpainon takia on 7,5 cm. Mittauksissa havaittiin, että kone värähtelee resonanssissaamplitudilla 1 cm kun alustan värähtelyn amplitudi on 0,25 cm.

A structure that can be idealized as a SDOF system has a mass 100 kg, a stiffness of 40 kN/m and a damping ratio of 0.10. If it is subjected to a harmonic dynamic force given by p(t) = 500 sin(15 t) N, determine (a) the dynamic amplification under steady-state conditions; (b) the maximum velocity of the steady state vibration; and (c) the maximum amplitude if the forcing frequency was equal to the system frequency (a resonant condition).
[6] An instrument panel weighing 30 lb is installed in a vehicle on a flexible mount that has an equivalent stiffness k = 400 lb/in and negligible damping. As a result of engine vibration, the vehicle vibrates with a steady-state amplitude of o.25 in at a frequency of 40 Hz. Determine the steady-state amplitude of vibration of the instrument panel.

An underdamped shock absorber is to be designed for a motor cycle of mass 200 kg(m). When the shock absorber is subjected to an initial vertical velocity due to a road bump, the resulting displacement-time curve is to be as indicated below. Find the necessary stiffness and damping constants of the shock absorber if the damped period of vibration is to be 10 sec(τd) and the amplitude x1is to be reduced to one-eighth in one half cycle.

please I want really correct accurate answer for this question
A vehicle is modelled as a combined mass-spring-damper system that oscillates in the vertical direction only. The driver of the vehicle travels along a road whose elevation varies sinusoidally as shown in Figure 2. The mass of the vehicle, which includes the driver, is 2500 kg. The stiffness and damping of the shocks are 40 kN/m and 3000 kg/s respectively. i. Determine the amplitude of vibration of the vehicle when it travels at a constant speed of 90 km/hr along the sinusoidal road. y/m 0.6 ►Velocity of vehicle m 0.4 ► Rigid massless tyre 0.2 distance (m) 20 60 80 -0.2 Figure 2
A damped single degree of freedom mass-spring system is excited at resonance by a harmonic forcing function which has an amplitude of 80 N. It was observed that the steady state amplitude of the forced vibration is 6 mm. It was also observed that when the frequency of excitation is three times the natural fre- quency of the system, the amplitude of the steady state vibration becomes 1 mm. Determine the stiffness coefficient k and the damping factor š.
