1.2096 Trial and error: by printing out (using any software) the damped free vibration solution under different damping coefficients, please choose the damping coefficient of a spring-mass- damper system with mass of 150 kg and stiffness of 20o0 N/m such that its response will die out after about 2 s, given a zero initial position and an initial velocity of 10 mm/s.
Consider a single degree of freedom (SDOF) with mass-spring-damper system
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...
