A rectangular beam has a cross section of b = 14 in., h = 22 in., and d = 19.5 in. It is reinforced with five No. 6 Grade 60 bars. The concrete strength is 9,100 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the cracking moment, Mcr.

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 2.25 kips/ft including its own self weight plus a uniform service (unfactored) live load of 1.2 kips/ft. The beam is reinforced with three No. 7 Grade 60 bars. The concrete strength is 2,500 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Using the effective moment of inertia, determine the immediate mid-span deflection of the beam due to the combined service loads (dead plus live).The effective moment of inertia Ie = 5,883.1 in.4.

A 23-year-old male presents to the office with a painful lesion on his lip. The NP diagnoses him with Herpese Simplex. What is the appropriate treatment?

A rectangular beam has a cross section of b = 18 in., h = 22 in., and d = 19.5 in. It is reinforced with four No. 7 Grade 60 bars. The concrete strength is 5,200 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the cracking moment, Mcr.

A rectangular beam has a cross section of b = 18 in., h = 28 in., and d = 25.5 in. It is reinforced with two No. 7 Grade 60 bars. The concrete strength is 5,800 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 five No. 7 Grade 60 bars. The concrete strength is 7,600 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 5.2627 in.

A 32-year-old female presents to the office for fatigue, poor appetite, progressive weakness and weight loss. On exam you notice hyperpigmentation on her knuckles, elbows and knees. You suspect that she has Addison’s disease. All of the following can assit you with determining this diagnosis except:

A simply supported beam with dimensions of b = 14 in., h = 22 in., d = 19.5 in., and L = 22 ft supports a uniform service (unfactored) dead load of 2.020833 kips/ft including its own self weight plus a uniform service (unfactored) live load of 1.4 kips/ft. The beam is reinforced with three No. 5 Grade 60 bars. The concrete strength is 4,900 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the effective moment of inertia, Ie.The cracked moment Mcr = 49.41 kip-ft, and the maximum applied bending moment due to the combined service loads (dead plus live) Ma = 207 kip-ft. The neutral axis location of the cracked beam (measured from the top of the beam) is 3.8833 in.

A simply supported beam with dimensions of b = 16 in., h = 22 in., d = 19.5 in., and L = 22 ft supports a uniform service (unfactored) dead load of 1.366667 kips/ft including its own self weight plus a uniform service (unfactored) live load of 0.8 kips/ft. The beam is reinforced with five No. 6 Grade 60 bars. The concrete strength is 4,300 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the effective moment of inertia, Ie.The cracked moment Mcr = 52.9 kip-ft, and the maximum applied bending moment due to the combined service loads (dead plus live) Ma = 131.1 kip-ft. The neutral axis location of the cracked beam (measured from the top of the beam) is 5.4711 in.

A rectangular beam has a cross section of b = 14 in., h = 26 in., and d = 23.5 in. It is reinforced with two No. 8 Grade 60 bars. The concrete strength is 8,800 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).
