A beam has dimensions of b = 16 in., h = 26 in., and d = 23.5 in. and is reinforced with 5 No. 7 bars. The concrete strength is 3,400 psi, and the yield strength of the reinforcement is 60,000 psi. Assuming the reinforcement has yielded, determine the tensile force T in the reinforcement.
Read DetailsA beam has dimensions of b = 14 in., h = 22 in., and d = 19.5 in. and is reinforced with 5 No. 5 bars. The concrete strength is 4,300 psi, and the yield strength of the reinforcement is 60,000 psi. Assuming the reinforcement has yielded, determine the depth to the neutral axis, c.

Read DetailsA beam has dimensions of b = 18 in., h = 30 in., and d = 27.5 in. and is reinforced with 2 No. 8 bars. The concrete strength is 5,800 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth to the neutral surface is c = 1.405644 in., determine the strain in the reinforcement.

Read DetailsA 15-year-old soccer player suffers a head injury during the opening play of a game. You assess for concussion & find he was confused as to what actually happened; he was never unconscious. He seemed OK when he walked off the field a couple minutes later & has a normal neurological exam now 15 minutes later. Your best recommendations:
