The cross-section of an isolated T beam is shown. Use \( f_{c}^{\prime}=6,000 \mathrm{psi} \) and \( f_{y}=60,000 \) psi. The beam is supported as a cantilever with a span of \( 15 \mathrm{ft} \). The beam supports its own weight, and a concentrated service live load equal to 15 kips at the tip of the cantilever. The live load is stationary. With proper calculations, calculate the spacing of #4 stirrups, and clearly show your final design.
