A beam has dimensions of b = 18 in., h = 30 in., and d = 27.5 in. and is reinforced with 3 No. 7 bars. The concrete strength is 4,600 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth to the neutral surface is c = 1.871374 in., determine the strain in the reinforcement.

A 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:

Most of our understanding of what a person is communicating to us when having a face to face conversation comes from the words they are saying.  

A beam has dimensions of b = 14 in., h = 28 in., and d = 25.5 in. and is reinforced with 3 No. 6 bars. The concrete strength is 7,300 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the nominal moment capacity, Mn, of the beam.

A beam is singly reinforced with the reinforcement in two rows. The bottom row contains 7 No. 8 bars at a depth of 18 in. The top row contains 3 No. 5 bars at a depth of 13 in. Determine the effective (centroidal) depth, d, of the steel.

(04.02 MC)  A coin is weighted so that the probability of tails is 0.58. The coin is tossed 25 times, and the number of times tails is shown is recorded. This procedure is repeated 150 times with the number of times tails is shown noted each time. What kind of distribution is simulated? (4 points)
