R15 / ww 25. (Forced Damped Vibrations: Particle) The 80-1bf block is attached to a 15 lbf/in spring, the end of which is subjected to a periodic support displacement 0.5 sin (8t) ft. Determine the amplitude of the steady-state horizontal motion of the block. What happens to the amplitude of the steady-state motion if (a) the block is doubled in weight?, (b the spring is doubled in stiffness? (c) Discuss your findings....
Mechanics of Machines and Vibrations Single Degree of Freedom- Forced Damped Vibration Problem 15 A vehicle of mass 1,500 kg is placed on a vibrating platform to test the condition of its shock absorbers. The platform vibrates with y 3sin40t mm and it is found that the relative amplitude of steady state of the vehicle is 3 mm. If the equivalent stiffness of the suspension is ke 310° N/m, determine the following:- i. Damping ratio, ii. Equivalent damping constant of...
