A beam has dimensions of b = 14 in., h = 30 in., d’ = 2.5 in., and d = 27.5 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 3,700 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 = 3.809 in. (depth of concrete stress block)Cc = 165.8 kips (compressive force in concrete)Cs = 23.8 kips (compressive force in steel)T = 189.6 kips (tensile force in steel)

At а lоcаl trаnsfer statiоn there is enоugh room for 3 garbage trucks to unload at a time. If trucks arrive at an average rate of 2 every 90 minutes, a.) what is the probability that in a two hour period at least one truck must wait to unload at this station? b.) What is the probability that in a one hour period exactly one truck arrives to unload and in the next one hour period another single truck arrives? c.) If the station is open for 8 hours a day, what is the approximate rate per day that trucks need to arrive at if we want the probability that NO trucks arrive over a two hour period to be 18%?
