Question details

Question3 A boy riding a bicycle can be modelled as a spring-mass-damper system with an equivalent weight, stiffness and damping constant of 800 N, 50kN/m and 1000 N s/m respectively The differential setting of the concrete blocks on the road caused the level surface to decrease suddenly, as indicated in figure Q3 If the speed of the bicycle is 5 m/s (18 km/h), determine the displacement of the boy in the vertical direction Assume that the bicycle is free of vertical vibration before encountering the step change in the vertical displacement [15] tnl cq keq FIGURE Q3
