Theory of Machine If ω/ωn is very high for a body vibrating under steady state vibrations, the phase angle for all values of damping factors, will tend to approach 360° 180° 90° 0° 360° 180° 90° 0° ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The equation of motion for a vibrating system with viscous damping is (d²x/dt²) + (c/m). (dx/dt) + (s/m). x = 0. If the roots of this equation are real, then the system will be Over-damped Critically damped Without vibrations Under damped Over-damped Critically damped Without vibrations Under damped ANSWER DOWNLOAD EXAMIANS APP
