A beam has dimensions of b = 16 in., h = 26 in., and d = 23.5 in. and is reinforced with 3 No. 5 bars. The concrete strength is 10,000 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the compressive stress block is a = 0.410294 in. and the strain in the reinforcement is εs = 0.108688, determine the strength φMn for this beam. Assume the transverse reinforcement is not spirals.

LISTENING COMPREHENSION (4 pts) The Travel Blog (Vocabulary: Travel and the Environment) José is a travel blogger. Listen to José describing things that he has seen and done while traveling. Listen to what he says and then select the corresponding statement.

A beam has dimensions of b = 18 in., h = 28 in., and d = 25.5 in. and is reinforced with 5 No. 6 bars. The concrete strength is 7,600 psi, and the yield strength of the reinforcement is 60,000 psi. Assuming the reinforcement has yielded, determine the depth to the neutral axis, c.

Write a comparison of inequality with the masculine and plural noun “turistas”: Comparison of tourist visits for Nicaragua and Costa Rica Año  Nicaragua (en millones) Costa Rica (en millones) 2022 0.5 1.3 2023 0.6 1.5 2024 0.3 1.8   Nicaragua tiene __________  __________  __________ Costa Rica.

The symbol Mn represents the _______.

One of the three basic assumptions in the theory of flexure for reinforce concrete is that the forces in the concrete and reinforcement can be computed from the deflection by using the stress-strain curves for concrete and steel.

At 25°C, the equilibrium constant Kc = 0.0012 for the reaction  B(aq) + C(aq)  ↔  2A(aq)     A solution of 0.80 M of B and 0.80 M of C is mixed and allowed to come to equilibrium. A student does the following steps below to calculate the equilibrium concentration of A.  There is one error in this calculation. Identify the step where the student made an error.  (keeping extra digits until the end of the calculation is not an error).

One of the four primary reasons for using compression reinforcement in beams is inadequate fire rating.

Which symbol represents the distance from the extreme compression fiber to the centroid of the longitudinal compression steel?
