The new tacoma narrows bridge reopened on october 14 1950, Ask an Expert

Academics

The new Tacoma Narrows Bridge, reopened on October 14, 1950, has the following data:

l= 2800 ft(between towers)

b=60 ft(width between cables)

k=280 ft(maximum sag of cables)

ω_t=8570 lb/lineal ft

J₀=(w_t/g)*P²(rotational mass moment of inertia)

Calculate the new cable tension, the cable torsional stiffness, the new vertical and torsion al vibration frequencies, and compare with previous values. (Assume a reasonable value for the radius of gyration p in determining the torsional mass moment of inertia.)
