A beam has dimensions of b = 14 in., h = 28 in., d’ = 2.5 in., and d = 25.5 in. It is reinforced with 2 No. 5 bars on the compression side and 4 No. 8 bars on the tension side. The concrete strength is 4,000 psi, and the yield strength of the reinforcement is 60,000 psi. For the results given below, determine the strength Mn for this beam.a = 3.569 in. (depth of concrete stress block)Cc = 167.8 kips (compressive force in concrete)Cs = 21.8 kips (compressive force in steel)T = 189.6 kips (tensile force in steel)

(04.03 MC) The probability that Babe Ruth hits a home run on any given at-bat is 0.12, and each at-bat is independent. Part A: What is the probability that the next home run will be on his fifth at-bat? (5 points) Part B: What is the expected number of at-bats until the next home run? (5 points) (10 points)

At 25°C, the equilibrium constant Kc = 0.0012 for the reaction B(aq) + C(aq) ↔ 2A(aq) A solution of 0.80 M of B and 0.80 M of C is mixed and allowed to come to equilibrium. A student does the following steps below to calculate the equilibrium concentration of A. There is one error in this calculation. Identify the step where the student made an error. (keeping extra digits until the end of the calculation is not an error).
