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?

A pipeline with an outside diameter of 500 mm and a wall thickness of 10 mm is pressurized to 1.8 MPa. Due to thermal expansion, a compressive force of 34 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 = 48 N is applied to a lever at the end of a 34-mm-diameter shaft. Force Q = 150 N is applied directly to the shaft. Determine the normal stress σy at point H. Let a = 120 mm and b = 215 mm.

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. 8 Grade 60 bars. The concrete strength is 3,700 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the assumed modulus of elasticity of the concrete, Ec.

A tank with an inside diameter of 370 mm, a length of 885 mm, and a wall thickness of 3.6 mm was designed to withstand a pressure of 685 kPa. If the outside of the tank has corroded such that the thickness is now 89% of the original value, what should the pressure now be limited to?

The pressure hull of a space station module has an inside diameter of 4.5 m, a length of 5.5 m, and a wall thickness of 2.6 mm. It is made from an aluminum alloy with a yield strength of 247 MPa. If the hull is successfully pressure tested to 195 kPa on Earth, determine the factor of safety with respect to yielding.

A pipeline with an outside diameter of 460 mm and a wall thickness of 11 mm is pressurized to 1.6 MPa. Due to thermal expansion, a compressive force of 20 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 = 41 N is applied to a lever at the end of a 34-mm-diameter shaft. Force Q = 925 N is applied directly to the shaft. Determine the normal stress σy at point K. Let a = 165 mm and b = 205 mm.

A simply supported beam with dimensions of b = 16 in., h = 28 in., d = 25.5 in., and L = 24 ft supports a uniform service (unfactored) dead load of 1.966667 kips/ft including its own self weight plus a uniform service (unfactored) live load of 1.3 kips/ft. The beam is reinforced with four No. 6 Grade 60 bars. The concrete strength is 8,200 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the effective moment of inertia, Ie.The cracked moment Mcr = 118.3 kip-ft, and the maximum applied bending moment due to the combined service loads (dead plus live) Ma = 235.2 kip-ft. The neutral axis location of the cracked beam (measured from the top of the beam) is 5.0301 in.

A 15-year-old female presents to the office with acne consisting of 25 comedones and 20 inflammatory lesions with no nodules. The patient can be classified as having which type of acne?
