Mechanics of Machines and Vibrations Single Degree of Freedom- Forced Damped Vibration Problem 15...
Single Degree of Freedom -Free Damped Vibration of Machines and Vibrations problem shows a lever with spring, mass and damper system. The lever has a moment p9 shows a lever with Agure so kgm2 pivoted at point O with a pulley of mass 4 kg with a radius r-0.5 m Vibration and and load mp4 kg. The load stioping between the puiley and cable supporting the load m. The stiffiess coefficient sippie spring isk=2x105 N/m. Calculate the following when the...
Consider a single degree of freedom (SDOF) with mass-spring-damper system subjected to harmonic excitation having the following characteristics: Mass, m = 850 kg; stiffness, k = 80 kN/m; damping constant, c = 2000 N.s/m, forcing function amplitude, f0 = 5 N; forcing frequency, ωt = 30 rad/s. (a) Calculate the steady-state response of the system and state whether the system is underdamped, critically damped, or overdamped. (b) What happen to the steady-state response when the damping is increased to 18000 N.s/m? (Hint: Determine...
can someone help me wuth these two questuons 22. (Forced Damped Vibrations: Particle) Prove the approximation for Quality Factor Q=fn/(t2 - fl) for determining the lightly damped coefficient of damping based on the measure natural frequency and the half-power power bandwidth (f2-fl). 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...
