Answer: The beam AB, consisting of a cast-iron plate of
Chapter 5, Problem 5.128(choose chapter or problem)
The beam AB, consisting of a cast-iron plate of uniform thickness b and length L, is to support the distributed load w(x) shown. (a) Knowing that the beam is to be of constant strength, express h in terms of x, L, and \(h_0\). (b) Determine the smallest value of h0 if L = 750 mm, b = 30 mm, \(w_0 = 300 \text{ kN/m}\), and \(\sigma_\text{all} = 200 \text{ MPa}\).
