When the force in a reinforcing bar changes from point to point along its length, there must be bond stresses between it and the concrete.

Rewrite with only sin x and cos x. cos 2x – sin x (6 points)

A rectangular beam has a cross section of b = 18 in., h = 24 in., and d = 21.5 in. It is reinforced with five No. 5 Grade 60 bars. The concrete strength is 6,400 psi (normal weight). The beam has Grade 60 No. 3 stirrups satisfying ACI 318-14 Sections 9.7.6.2.2 and 9.6.3.3. Determine the strength φMn for this beam.

Determine algebraically whether the function is even, odd, or neither even nor odd. f(x) = -8×3 + 6x (5 points)

For economy, some of the bars can be terminated or cutoff where they are no longer needed.
