Q8.  A nurse is reviewing the medical record of a client who has been on levothyroxine for several months. Which of the following findings indicates a therapeutic response to the medication?

A pipeline with an outside diameter of 420 mm and a wall thickness of 12 mm is pressurized to 2.2 MPa. Due to thermal expansion, a compressive force of 21 kN is generated along the length of the pipes. Determine the normal stress along the length of the pipes. Ignore the bending stresses due to the weight of the pipes and the fluid that they contain.

Force P = 42 N is applied to a lever at the end of a 31-mm-diameter shaft. Force Q = 195 N is applied directly to the shaft. Determine the magnitude of the shear stress τyz at point K. Let a = 180 mm and b = 235 mm.

A tank with an inside diameter of 365 mm, a length of 930 mm, and a wall thickness of 3.6 mm was designed to withstand a pressure of 750 kPa. If the outside of the tank has corroded such that the thickness is now 90% of the original value, what should the pressure now be limited to?

A rectangular beam has a cross section of b = 16 in., h = 26 in., and d = 23.5 in. It is reinforced with five No. 5 Grade 60 bars. The concrete strength is 4,900 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the transformed cross-sectional area of the bars, Ast.

A tank with an inside diameter of 345 mm, a length of 740 mm, and a wall thickness of 4.0 mm was designed to withstand a pressure of 660 kPa. If the outside of the tank has corroded such that the thickness is now 88% of the original value, what should the pressure now be limited to?

A 495 N person stands at the end of a 1.48 m cantilever beam. The beam has a base of 85 mm and a height of 160 mm. Determine the maximum bending stress in the beam.

Force P = 41 N is applied to a lever at the end of a 31-mm-diameter shaft. Force Q = 800 N is applied directly to the shaft. Determine the normal stress σy at point K. Let a = 155 mm and b = 230 mm.

  A population of cardinals grew geometrically during a 5-year period. During this period, the annual rate of increase equaled two (λ = 2). If the population consisted of 20 individuals at the beginning of year 1, what was the size of the population at the beginning of year 5?

A 37 year old female presents to the office complianing of feeling cold all the time, constipation, fatigue and a missed period. On exam you note thinning hair, decreased deep tendon reflexes and bradycardia. A serum pregnany test is negative and her fasting glucose is 84. What is the likely cause of her symptoms?
