A simply supported beam with dimensions of b = 18 in., h = 22 in., d = 19.5 in., and L = 21 ft supports a uniform service (unfactored) dead load of 1.4125 kips/ft including its own self weight plus a uniform service (unfactored) live load of 0.8 kips/ft. The concrete is normal-weight concrete. The beam is reinforced with 2 No. 5 bars. The concrete strength is 9,100 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the maximum applied bending moment due to the combined service loads (dead plus live), Ma.      

Find the exponential function that satisfies the given conditions: Initial value = 56, decreasing at a rate of 0.42% per week (5 points)  

Smaller diameter aggregate creates a rougher crack surface, allowing higher shear stresses to be transferred across cracks.

In deformed reinforcing bars, adhesion and lateral friction are insignificant sources of bond strength.
