Wobbly Bridge Second order ODE associated with the bricge is given as 105 kg, ka 5 x 104 kg/sec and A 107 kg/sec2 1. Compute k at critical level of damping, how does it compare with k,a where M4x 2. Effective forcing from each pedestrian was 300ż and for N the number of people the above equation becomes Compute the number of people on the bridge which will cause no damping.
