MACARENA: Hola, José. ¿Qué tal tu viaje a Costa Rica? JOSÉ: Estupendo. Mi novia y yo pasamos una semana en las [q5] en el interior del país. Nos gusta mucho la playa, pero también nos encanta [q6] en caminos bonitos. MACARENA: ¡Qué bien! No sabía que os gustaba caminar y hacer vías ferratas. JOSÉ: Bueno, somos principiantes, pero es que hay muchas actividades para hacer allí… Nuestra excursión favorita fue cuando exploramos una [q7] con linternas. También nos encantan los animales y pudimos [q8] a caballo y [q9] las aves desde una distancia recomendada. MACARENA: ¡Me alegro! Estoy pensando en mis próximas vacaciones y quiero ir a un destino como Costa Rica, donde cuidar la [q10] es muy importante para el turismo. JOSÉ: Sí, ¡Costa Rica es un destino perfecto! El gobierno y la industria turística trabajan juntos para limitar la [q11] que dejan los turistas.

A beam has dimensions of b = 16 in., h = 30 in., and d = 27.5 in. and is reinforced with 5 No. 5 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.

En el mes de julio llovió mucho y hubo una [q12] cerca de Bogotá. El exceso de agua dañó una zona muy turística.

A beam has dimensions of b = 16 in., h = 26 in., and d = 23.5 in. and is reinforced with 2 No. 7 bars. The concrete strength is 6,400 psi, and the yield strength of the reinforcement is 60,000 psi. Assuming the reinforcement has yielded, determine the tensile force T in the reinforcement.

In design, there is one unique answer. One determines the beam strength given several factors such as concrete strength, cross section, reinforcement size, location, and yield strength.

Consider the following timeline detailing a stream of cash flows: 4.1-7.jpg If the current market rate of interest is 10%, then the present value (PV) of this stream of cash flows is closest to ________.

A beam is singly reinforced with the reinforcement in two rows. The bottom row contains 6 No. 7 bars at a depth of 22 in. The top row contains 4 No. 6 bars at a depth of 16.5 in. Determine the effective (centroidal) depth, d, of the steel.

A beam has dimensions of b = 18 in., h = 26 in., and d = 23.5 in. and is reinforced with 3 No. 8 bars. The concrete strength is 7,900 psi, and the yield strength of the reinforcement is 60,000 psi. Assuming the reinforcement has yielded, determine the tensile force T in the reinforcement.

Reasons for adding compression reinforcement include which of the following?

One of the four primary reasons for using compression reinforcement in beams is decreased cost.
