A 7 year old boy is in for a well child check and his mom expresses concern that he defies her and refuses to do nearly everything she asks him to do. This occurs over simple requests like asking him to hang up his coat or carry his dishes to the kitchen counter after eating. Which strategy would be the best to redirect his mistaken goal?

You are considering a beam design that has dimensions of b = 16 in., h = 26 in., and d = 23.5 in. The beam is singly reinforced with all of the reinforcement in a single row. The concrete strength is 3,400 psi, and the yield strength of the reinforcement is 60,000 psi. What cross-sectional area of reinforcement is needed to achieve a strain in the reinforcement of 0.0075?
