A simply supported beam with dimensions of b = 18 in., h = 26 in., d = 23.5 in., and L = 20 ft supports a uniform service (unfactored) dead load of 1.7875 kips/ft including its own self weight plus a uniform service (unfactored) live load of 1.0 kips/ft. The beam is reinforced with five No. 8 Grade 60 bars. The concrete strength is 7,300 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the effective moment of inertia, Ie.The cracked moment Mcr = 108.3 kip-ft, and the maximum applied bending moment due to the combined service loads (dead plus live) Ma = 139.4 kip-ft. The neutral axis location of the cracked beam (measured from the top of the beam) is 6.6383 in.

Axial compression tends to _______ shear strength?

Cracks that lead to splitting along the reinforcement are known as _______ cracks.

Bond stresses must be absent whenever the stress or force in a reinforcing bar changes from point to point along the length of the bar.

The nurse is administering a medication that is described as a beta 2 adrenergic agonist. What would the nurse expect as the intended effect of this medication?

When large amounts of steel are to be used, they can be bundled together. This increases the effective perimeter of each bar.

Which of the following is the most appropriate regarding inventory turnover? Inventory turnover increases as average inventory decreases, while other things remain the same. Inventory turnover is an efficiency measure. Inventory turnover is unaffected by changes in annual sales.

This term refers to the center of mass being located over the base of support. Moving the center of mass in one direction or another places the rider out of it. 

A rectangular beam has a cross section of b = 18 in., h = 30 in., and d = 27.5 in. It is reinforced with five No. 5 Grade 60 bars. The concrete strength is 8,500 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the assumed modulus of elasticity of the concrete, Ec.

A simply supported beam with dimensions of b = 14 in., h = 26 in., d = 23.5 in., and L = 22 ft supports a uniform service (unfactored) dead load of 1.479167 kips/ft including its own self weight plus a uniform service (unfactored) live load of 0.9 kips/ft. The beam is reinforced with two No. 6 Grade 60 bars. The concrete strength is 7,300 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 = 5,939.7 in.4.
