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. If the depth of the neutral axis is c = 4.481 in., determine the force in the compression reinforcement, Cs.

The basic strength requirement from ACI 318 is “Factored load effects ​≤ Reduced nominal strength.”

This child’s mother wants no more than 3 shots given today (assume not are combined); therefore, based on common recommendations your best plan for immunizations today would be:

(06.03 MC)Which of the following best describes reproductive structures common to both gymnosperms and angiosperms?

Faisal has $12,000 in his savings account and can save an additional $3,600 per year. If interest rates are 12%, how long will it take his savings to grow to $47,000?

(05.03 LC)A scientist makes a claim that two hominid species have a common evolutionary ancestor. Which of the following must happen to ensure this claim can be considered valid?

(05.02 HC)A small population of red birds lived in a habitat that did not undergo changes for a long period of time. The birds were geographically isolated from other red birds. Predict the effects of natural selection on this population of birds.

A beam has dimensions of b = 18 in., h = 28 in., and d = 25.5 in. and is reinforced with 2 No. 6 bars. The concrete strength is 3,400 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.

A 7 year old boy is in for a well child check and his mom expresses concern that he defies her and refuses to do nearly everything she asks him to do. This occurs over simple requests like asking him to hang up his coat or carry his dishes to the kitchen counter after eating. Which strategy would be the best to redirect his mistaken goal?
