Question

$\text{If}\frac{\omega }{{\omega }_n}\text{is very high for a body vibrating under steady state vibration, the phase angle for all values of damping factors will tend to approach}$

• A. $0^{\circ }$
• B. $0^{\circ }$
• C. ${180}^{\circ }$
• D. ${45}^{\circ }$

Answer 1

The correct option is C ${180}^{\circ }$


$\text{At very high}\frac{\omega }{{\omega }_n}\text{phase angle}\left(\varphi \right)\text{tends to}{180}^{\circ }$
