In a reinforced concrete beam, the flexural compressive forces are resisted by _______, while the flexural tensile forces are provided by _______.

In the acronym “Park SMART” ­– the letter M stands for:

The development length for a hooked bar is generally shorter than that for a headed bar.

Determine the bar-spacing factor, cb, for a simply supported rectangular beam with b = 24 in. and No. 3 stirrups. This beam has three No. 9 bars as longitudinal reinforcement. The clear cover is 1.9 in.

Paso 2 (6 pts) (1 pt per sentence: 0.5 pts meaning, 0.5 pts form)  Nuria is talking to her mother and describing the day she and her friends had yesterday at Penn State. Write what she says with the correct forms of the preterit tense using the appropriate verb. Each verb may ONLY be used once.

Find the vertex of the graph of the function. (5 points) f(x) = (x + 6)2 + 3  

Determine the casting-position modification factor, ψt, for a rectangular beam with b = 16 in. and d = 20 in., five galvanized No. 7 Grade 60 tension-reinforcement bars placed in the top of the beam, and No. 3 Grade 60 stirrups located every 12 in. along the span. Assume 4,000-psi normal-weight concrete and a clear cover of 1.5 in.

If you are registered for KINES 12 you can opt not to snowboard and can instead join KINES 11 for skiing.

The stress in the reinforcement goes to zero at a crack.

A simply supported beam with dimensions of b = 18 in., h = 24 in., d = 21.5 in., and L = 19 ft supports a uniform service (unfactored) dead load of 2.05 kips/ft including its own self weight plus a uniform service (unfactored) live load of 0.8 kips/ft. The beam is reinforced with three No. 7 Grade 60 bars. The concrete strength is 10,000 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the effective moment of inertia, Ie.The cracked moment Mcr = 108 kip-ft, and the maximum applied bending moment due to the combined service loads (dead plus live) Ma = 128.6 kip-ft. The neutral axis location of the cracked beam (measured from the top of the beam) is 4.1961 in.
