$($adapted from Hibbeler $10$th ed$.$ prob. $6-131)$ Determine the maximum uniform distributed load w$0$ that can be supported by the reinforced concrete beam if the allowable tensile stress for the steel is $28$ ksi and the allowable compressive stress for the concrete is $3$ ksi. Assume the concrete cannot support a tensile stress. Take Esteel $=29$ Mpsi, Econcrete $=3\mathrm{.}6$ Mpsi.
