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
