A beam has dimensions of b = 14 in., h = 24 in., and d = 21.5 in. and is reinforced with 4 No. 6 bars. The concrete strength is 5,500 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.

(04.02 HC)The table below shows salinity tests from coastal Louisiana following a salt water influx during hurricanes Katrina and Rita. If efforts are not made to reduce the salinity in these areas, what is the most likely long term effect?

A beam has dimensions of b = 14 in., h = 22 in., and d = 19.5 in. and is reinforced with 3 No. 8 bars. The concrete strength is 6,100 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.

One of the four primary reasons for using compression reinforcement in beams is increased fatigue life.

The most likely cause of sudden cardiac death in the young athlete is:

For economic reasons, reinforced concrete should be designed to be _______.

While there are many possible etiologies for premature thelarche, the most likely explanation is:

(05.01 LC)Giraffes use their extremely long necks to reach tall trees, giving them a food source for which they have few competitors. What can you conclude about natural selection from this observation?

  (05.03 MC)Skulls of (1) Modern gorilla, (2) Australopithecus afarensis, (3) Homo erectus, (4) Homo neanderthalensis, (5) Modern humanWhich of the following can be inferred from the differences between the skulls of Australopithecus afarensis and Homo neaderthalensis?
