A rectangular beam has a cross section of b = 16 in., h = 24 in., and d = 21.5 in. It is reinforced with four No. 5 Grade 60 bars. The concrete strength is 9,400 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the modulus of rupture of the concrete, fr.

A simply supported beam with dimensions of b = 14 in., h = 30 in., d = 27.5 in., and L = 16 ft supports a uniform service (unfactored) dead load of 2.1375 kips/ft including its own self weight plus a uniform service (unfactored) live load of 1.2 kips/ft. The beam is reinforced with four No. 8 Grade 60 bars. The concrete strength is 10,000 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the effective moment of inertia, Ie.The cracked moment Mcr = 131.3 kip-ft, and the maximum applied bending moment due to the combined service loads (dead plus live) Ma = 106.8 kip-ft. The neutral axis location of the cracked beam (measured from the top of the beam) is 6.8815 in.

Force P = 43 N is applied to a lever at the end of a 32-mm-diameter shaft. Force Q = 165 N is applied directly to the shaft. Determine the magnitude of the shear stress τyz at point K. Let a = 135 mm and b = 225 mm.

A rectangular beam has a cross section of b = 16 in., h = 22 in., and d = 19.5 in. It is reinforced with five No. 8 Grade 60 bars. The concrete strength is 8,200 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the cracking moment, Mcr.

A simply supported beam with dimensions of b = 14 in., h = 22 in., d = 19.5 in., and L = 20 ft supports a uniform service (unfactored) dead load of 1.520833 kips/ft including its own self weight plus a uniform service (unfactored) live load of 0.8 kips/ft. The beam is reinforced with three No. 7 Grade 60 bars. The concrete strength is 3,100 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 = 4,323.9 in.4.

Epiglottitis in a child can be resolved with home remedies and does not require medical attention. 

A bacterial sample from a patient was gram stained using standard protocol.  The results of the gram stain showed pink rods and purple circles under the microscope.  If you were to streak this patient sample on nutrient agar plates to isolate colonies, which of the following, plate A or plate B, would best represent the sample?  

The PAT consists of assessing the appearance of the patient, the patient’s work of breathing and their blood pressure. 

A simply supported beam with dimensions of b = 16 in., h = 28 in., d = 25.5 in., and L = 23 ft supports a uniform service (unfactored) dead load of 2.266667 kips/ft including its own self weight plus a uniform service (unfactored) live load of 1.4 kips/ft. The beam is reinforced with five No. 6 Grade 60 bars. The concrete strength is 10,000 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 = 9,103.4 in.4.

A 505 N person stands at the end of a 1.42 m cantilever beam. The beam has a base of 95 mm and a height of 160 mm. Determine the maximum bending stress in the beam.
