A 124-mm-long beam supports a load of P = 48 N at midspan. The cross section is rectangular with width b = 25 mm and height h = 40 mm. Determine the magnitude of the horizontal shear stress at the centroid of the cross section.

Use the Rational Zeros Theorem to write a list of all potential rational zeros. (5 points) f(x) = 13×3 + 23×2 + 2x – 26  

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.

A rectangular beam with cross section b = 16 in., h = 20 in., and d = 17.5 in. supports a total factored uniform load of 1.00 kips/ft, including its own dead load. The beam is simply supported with a 21-ft span. It is reinforced with four No. 5 Grade 60 bars, two of which are cutoff between midspan and the support and two of which extend 10 in. past the centers of the supports. The concrete strength is 6,300 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. The strength of the four bars is φMn = 95.23 kip-ft, and the strength of the remaining two bars is φMn = 48.22 kip-ft. If the distance from the support to the theoretical cutoff point is 6.784 ft, determine the distance from the support to the actual cutoff point (i.e. use ACI 318-14 Section 9.7.3.3).

Determine the bar-spacing factor, cb, for a simply supported rectangular beam with b = 20 in. and No. 3 stirrups. This beam has three No. 7 bars as longitudinal reinforcement. The clear cover is 1.6 in.

Determine the bar-spacing factor, cb, for a simply supported rectangular beam with b = 16 in. and No. 3 stirrups. This beam has three No. 7 bars as longitudinal reinforcement. The clear cover is 1.9 in.
