A 34-year-old male with no past medical history presents to the office with two furuncles approximately 3.5cm in diameter on the left posterior thigh. The patient reports the lesions have been present for the past 4 days and have been increasing in size. He has no fever, chills or drainage from the lesions. On exam they are mildly erythematous and indurated. What is the best treatment plan for this patient?

Compute the maximum bar spacing, s, to control for cracks in a one-way slab with 2.3 in. of clear cover and f​y​ = 70 ksi.

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 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.

Compute the maximum bar spacing, s, to control for cracks in a one-way slab with 2.4 in. of clear cover and f​y​ = 52 ksi.

A rectangular beam has a cross section of b = 14 in., h = 30 in., and d = 27.5 in. It is reinforced with three No. 5 Grade 60 bars. The concrete strength is 6,100 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the cracked moment of inertia, Icr. The neutral axis location of the cracked beam (measured from the top of the beam) is 4.4649 in.

A rectangular beam has a cross section of b = 16 in., h = 24 in., and d = 21.5 in. It is reinforced with three No. 5 Grade 60 bars. The concrete strength is 7,900 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the transformed cross-sectional area of the bars, Ast.

A rectangular beam has a cross section of b = 18 in., h = 22 in., and d = 19.5 in. It is reinforced with two No. 6 Grade 60 bars. The concrete strength is 9,100 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the neutral axis location of the cracked beam (measured from the top of the beam).

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 simply supported beam with dimensions of b = 18 in., h = 24 in., d = 21.5 in., and L = 23 ft supports a uniform service (unfactored) dead load of 1.75 kips/ft including its own self weight plus a uniform service (unfactored) live load of 0.9 kips/ft. The beam is reinforced with four No. 5 Grade 60 bars. The concrete strength is 5,200 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the effective moment of inertia, Ie.The cracked moment Mcr = 77.88 kip-ft, and the maximum applied bending moment due to the combined service loads (dead plus live) Ma = 175.2 kip-ft. The neutral axis location of the cracked beam (measured from the top of the beam) is 4.1113 in.
