3. A 17-ft-span simply supported beam has a clear span of \( 16 \mathrm{ft} \) and carries uniformly distributed dead and live loads of \( 4.5 \mathrm{~K} / \mathrm{ft} \) and \( 3.75 \mathrm{~K} / \mathrm{ft} \), respectively. The dimensions of the beam section and steel necessaryent are shown in the figure below. Check the critical section for shear and design the shear reinforce reinforcement. Given \( f_{c}=3 \mathrm{ksi} \) normal-weight concrete and \( f_{n t}=60 \mathrm{ksi} \). Design the
