2. For the following section assume concrete with compressive strength of 5,000 psi and rein: steel bars with yield strength of 60 ksi. Address the following assuming three cases for reinforcement area given below: a. Calculate the balanced reinforcement ratio p, and tension-controlled reinforcement ratio for the cross section. Then specify failure mode (ductile/brittle) for each case. b. c. Case 1: A.-6.00 in² Case 1: A.-5.00 in² Case 2: A, 4.00 in² Case 3: A, 3.00 in² For each case, calculate the Nominal Strength, M. Also find the strain in the steel bars. Calculate the reduction factor, and design moment strength, QM, for each case. d. Using your findings in the previous parts, complete the table below. Comment on the effici of using more reinforcement in obtaining higher design moment strength based on the last t columns of the table. h=20" b=12" d=17"

Hand written and clean writing please

what is the maximum bending stress ?

Looking for assistance with Mohr Circle. I'm not asking for the whole problem to be worked, but can someone walk me through test1 (data for it is at the bottom of the screen) for total stress mohr circle

please solve the following problem on pencil and paper so I can understand. Please show all work.
