Given a rectangular reinforced concrete beam with \( A_s = 15 \text{ in}^2 \), \( f_y = 70 ext{ ksi} \), \( f_{c'} = 5 ext{ ksi} \), \( b = 10 ext{ in} \), \( d = 30 ext{ in} \), determine the balanced steel ratio.
💡 Hint: Make sure to convert ksi to the correct units if needed.
Discuss the effects of using an excessive steel ratio in a structural design.
💡 Hint: Think about how too much steel could affect the manner of loading.
