A simply supported, rectangular, reinforced concrete beam having d = 24 in. and b = 15 in. supports a uniformly distributed load wu of 7.50 kips/ft as shown.
The given load includes the beam weight. Assume No. 3 single-loop stirrups. The concrete strength is 4000 psi and the steel is grade 60.
a. Select the stirrup spacing to use at the critical section (d distance from the face of support).b. Determine the maximum stirrup spacing allowed for this beam.c. Using the two spacings determined in parts (a) and (b), devise an appropriate stirrup spacing layout for this beam.
Compare the inlet steam mass and volume flow rates in pound mass per second and cubic feet per second of (a) a fossil-fuel power plant turbine having a polytropic efficiency of 0.90 and receiving steam at 2400 PSIA and 1000F and (b) a nuclear power p..
As a game, slide a matchbook across a table, trying to make it stop at some predefined point on each attempt. Measure the distance from the starting point to the stopping point. Repeat this 10, 20, through 50 times. Plot the frequency distribution fr..
