A) Mass of the vehicle, stiffness of the suspension spring, speed of the vehicle, wavelength of the roughness curve
B) Speed of the vehicle only
C) Speed of the vehicle and the stillness of the suspension spring
D) Amplitude of the undulations
Correct Answer: A
Solution :
\[\beta =\frac{\omega }{{{\omega }_{n}}},\] \[{{\omega }_{n}}=\sqrt{\frac{k}{m}},\,\,\omega =\frac{v}{\lambda }\] Where v = vehicle speed, \[\lambda \,\,=\,\,\]wave length of rod undulations \[\therefore \,\,\,\,\,\,\,\,\,\,\,\beta \,\,=\,\,f\,(m,k,v,\lambda )\]
