A load of (5000 mathrm{~N}) resulted in a static displacement of (0.05 mathrm{~m}) in a composite structure.

Question:

A load of $5000 \mathrm{~N}$ resulted in a static displacement of $0.05 \mathrm{~m}$ in a composite structure. A harmonic force of amplitude $1000 \mathrm{~N}$ is found to cause a resonant amplitude of $0.1 \mathrm{~m}$. Find

(a) the hysteresis-damping constant of the structure,

(b) the energy dissipated per cycle at resonance,

(c) the steady-state amplitude at one-quarter of the resonant frequency, and

(d) the steady-state amplitude at thrice the resonant frequency.
