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.

(06.07 MC)  The number of cavities in school-aged children and size of vocabulary are known to have a strong negative association. Toby concluded that the number of cavities causes a decrease in vocabulary. Is Toby’s conclusion valid? Explain. (4 points)

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

A beam has dimensions of b = 18 in., h = 22 in., and d = 19.5 in. and is reinforced with 3 No. 8 bars. The concrete strength is 4,600 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the compressive stress block is a = 2.02046 in. and the strain in the reinforcement is εs = 0.020742, determine the strength φMn for this beam. Assume the transverse reinforcement is not spirals.

A beam has dimensions of b = 14 in., h = 30 in., and d = 27.5 in. and is reinforced with 4 No. 6 bars. The concrete strength is 9,400 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth to the neutral surface is c = 1.452365 in., determine the strain in the reinforcement.

A beam has dimensions of b = 16 in., h = 30 in., and d = 27.5 in. and is reinforced with 4 No. 6 bars. The concrete strength is 5,800 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the nominal moment capacity, Mn, of the beam.

(04.05 LC)  Daphne’s teacher told her that the standardized score (z-score) for her history exam, as compared to the exam scores of other students in the course, is 2.50. Which of the following is the best interpretation of this standardized score? (4 points)

Ms. Taft has brought her three-year-old son Michael to clinic today for a well child exam and there are no stated concerns at first asking. History reveals that Michael’s parents have recently divorced. Michael and his mom have relocated to your community for her job, and they live alone in a small, two-bedroom house built in 2003. Dad is about 50 miles away, but he intends to stay involved. Additional information indicates that Michael is a very picky eater and prefers beverages (milk, juice, and water), he’s currently sleeping with mom (which mom is not happy about), and he’s showing absolutely no interest in toilet training (which Mom is also not happy about). Past medical history and family medical history are noncontributory. Review of systems and physical exam suggest no medical concerns. Developmental screening is within normal limits using the Ages & Stages Questionnaire. Immunizations are up-to-date.                                                                                                                                                                                                                          Obviously, there is much additional information that would be helpful, but write an assessment that reflects your basic thoughts identifying all issues that ideally need to be addressed. Include routine health supervision as well as any additional issues you wish to address. Then, create a succinct, but detailed, plan to accompany your assessment, be sure to include rationale.   Assessment:   1.   2.   3.   4.   5.   Plan: Rationale: Considering all you’ve learned about well childcare and psychosocial issues, prepare a rationale so that you reflect knowledge of why you have decided on your plan of action. Number your rationale to correspond to your plan.

Tell me about a joint/muscle group that you feel hinder your day to day living or performance.    Then please list 2 different methods to improve mobility around that joint/muscle group – explain each method you are using to improve mobility and how it works.
