When a body is subjected to transverse vibrations, the stress-induced in a body will be

The natural frequency (in Hz) of free longitudinal vibrations is equal to

In under damped vibrating system, if x₁ and x₂ are the successive values of the amplitude on the same side of the mean position, then the logarithmic decrement is equal to

The equation of motion for a vibrating system with viscous damping is

$\frac{d^{2}x}{d{t}^2}+\frac{c}{m}\times \frac{dx}{dt}+\frac{s}{m}\times x=0$

If the roots of this equation are real, then the system will be
