A weightless cantilever supports a concentrated service load of magnitude $\mathrm{P}$ shown. The beam is a reinforced concrete beam with both flexure and transverse steel. Neglecting load factors, if the allowable flexural capacity is $140\mathrm{ft}?\mathrm{kips}$ and the allowable shear capacity is $5.8\mathrm{kips}$, what is the maximum allowable magnitude of P?
