can someone help me with these 2 questions? R15 / ww 25. (Forced Damped Vibrations: Particle)...
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...
Consider a damped forced mass-spring system with m = 1, γ = 2, and k = 26, under the influence of an external force F(t) = 82 cos(4t). a) (8 points) Find the position u(t) of the mass at any time t, if u(0) = 6 and u 0 (0) = 0. b) (4 points) Find the transient solution uc(t) and the steady state solution U(t). How would you characterize these two solutions in terms of their behavior in time?...
