Question: a boy riding a bicycle can be modeled as a...

Question details

A boy riding a bicycle can be modeled as a spring-mass-damper system with an equivalent weight, stiffness and damping constant of 800N, 50,000N/m, and 1,250N-s/m, respectively. Due to the different setting of the concrete blocks on the road, the level surface decreases suddenly as indicated in Fig. 4. Assume that the bicycle is free of vertical vibration before encountering the step change on the road surface, determine the vertical displacement of the boy caused by the step change in the road surface.

Q5. A boy riding a bicycle can be modeled as a spring-mass-damper system with an equivalent weight, stiffness and damping constant of 800N, 50,000N/m, and 1,.250N-s/m, respectively. Due to the different setting of the concrete blocks on the road, the level surface decreases suddenly as indicated in Fig. 4. Assume that the bicycle is free of vertical vibration before encountering the step change on the road surface, determine the vertical displacement of the boy caused by the step change in the road surface. eq 0 cq cnn Figure 4
