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.
