![1. Follow procedure used in class. Use reinforcing ratio rho as specified in class (Ignore rho
specified in the problems).
2. For cantilever beams assume depth as L/5 to estimate beam weight.
3. Remember that in cantilever beams tension is at the top.
4. If reinforcement doesn't fit in one layer place reinforcement in 2 layers. Remember that the
distance d is to the centroid of the reinforcement.
5. Do NOT use bars larger than #11](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F78f15e23-b668-48b1-99de-5d673f5cfa1f%2F227a9e4e-5e63-4d14-a325-a78db8658757%2Fdsos4d9_processed.png&w=3840&q=75)
