A beam is singly reinforced with the reinforcement in two rows. The bottom row contains 6 No. 8 bars at a depth of 22 in. The top row contains 2 No. 5 bars at a depth of 17 in. Determine the effective (centroidal) depth, d, of the steel.

Compute the maximum bar spacing, s, to control for cracks in a one-way slab with 2.1 in. of clear cover and f​y​ = 58 ksi.

Who is regarded as the “father of advertising art” and was the first American known to use illustrations in ads?

A rectangular beam has a cross section of b = 14 in., h = 30 in., and d = 27.5 in. It is reinforced with five No. 7 Grade 60 bars. The concrete strength is 2,500 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the cracking moment, Mcr.

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.
