Most concrete design codes specify a maximum usable compressive strain at which the nominal moment strength of the section is to be calculated. For ACI 318, this maximum usable strain value is 0.003.

Eliminate the parameter. x = t – 3, y = t2 + 5 (5 points)

Two forces with magnitudes of 90 and 50 pounds act on an object at angles of 30° and 160°, respectively. Find the direction and magnitude of the resultant force. Round to two decimal places in all intermediate steps and in your final answer. (5 points)

You are considering a beam design that has dimensions of b = 16 in., h = 28 in., and d = 25.5 in. The beam is singly reinforced with all of the reinforcement in a single row. The concrete strength is 8,800 psi, and the yield strength of the reinforcement is 60,000 psi. What cross-sectional area of reinforcement is needed to achieve a strain in the reinforcement of 0.0075?

A beam has dimensions of b = 16 in., h = 28 in., and d = 25.5 in. and is reinforced with 3 No. 8 bars. The concrete strength is 6,400 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the strength Mn for this beam.

Your next patient is a 36-year-old female coming into the clinic today to see you in your primary care clinic for an exacerbation of her psoriasis. Her psoriasis was diagnosed in middle school. It seems that her lesions are getting thicker, and scalier as she gets older. She has been using different topical treatments for years and she is wondering if there is any “new treatment”.  She does not have any other health issues. She is excited about spending more time outside during the spring. She loves to run and do other outdoor activities.  Which of the following statements is true about psoriasis?

A beam has dimensions of b = 16 in., h = 24 in., and d = 21.5 in. and is reinforced with 3 No. 6 bars. The concrete strength is 4,000 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the nominal moment capacity, Mn, of the beam.

A 56-year-old female with non-ischemic heart failure and hypertension presents to the office for a routine follow-up. Her last hospitalization for a congestive heart failure (CHF) with HFrEF (reduced ejection fraction) exacerbation was two years ago. Currently, she has is not complaining of shortness of breath, orthopnea, leg edema, or chest pain. She has been following a low-salt diet and does not drink alcohol. Her medications are carvedilol and a baby aspirin. Her home blood pressure measurements have ranged from 140-150/80-90 mmHg. Her physical exam findings are notable for a blood pressure of 150/90 mmHg. Her pulse is 60 beats/minute with S1S2 with no murmurs or gallops. Her respiratory rate is 12/minute. Her jugular venous pulse and pressure (JVP) is within the normal range and her lungs are clear bilaterally. Her point of maximal impulse (PMI) is laterally displaced. What medication should you add that can also improve her mortality from heart failure?

Whose work proved conclusively that spontaneous generation of life from nonlife was not possible?

You are in clinic working with an older patient reviewing their medications.  You are concerned about polypharmacy issues and are working with this patient on reducing doses or stopping any medications that may be causing harm or no longer benefit this patient.    Health care providers should consider patient/caregiver perspectives on goals of therapy.  They need to include views on medications and chronic conditions, preferences and priorities regarding prescribing to slow disease progression, prevent health decline, and address symptoms. Which of the following is NOT a true statement regarding polypharmacy?
