Determine the displacement amplitude (X) of a simple model of a motorbike in metres. (Express your answer to 3dp)

The vehicle and

rider have a mass of 118.8 kg. The system has a damping ratio of ξ =

0.1. The vehicle speed, v is 10.6 km/h, and the road surface can be

assumed to vary sinusoidally with an amplitude of 0.06m, and

wavelength of 6.8m.

The suspension stiffness, k, which is given in kN/m and is the missing number of the matrix shown in Figure 2 which follows a simple sequence.

 3x3 matrix, k11 is missing , k12 = 20, k13 = 30, k21 = 100, k22 = 200, k23 = 300, k31 = 1000, k32 = 2000 and k33 = 3000
