During serviceability calculations, it is common to ignore the presence of compression reinforcement.

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

Determine the size modification factor, ψs, for a rectangular beam with b = 16 in. and d = 23 in., three galvanized No. 6 Grade 60 tension-reinforcement bars placed in the top of the beam, and No. 3 Grade 40 stirrups located every 12 in. along the span. Assume 8,000-psi normal-weight concrete and a clear cover of 2 in.

An object is thrown straight down at 5.0 m/s from the top of a 125 tall building.  How long does it take the object to hit the ground?

Verbal communication is expressed by posture, facial expressions, actions or physical behavior.

Tied columns cannot be circular-shaped.

A rectangular beam has a cross section of b = 16 in., h = 26 in., and d = 23.5 in. It is reinforced with three No. 5 Grade 60 bars. The concrete strength is 4,300 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the gross moment of inertia, Ig, for the beam.

The nurse is assessing a 45-year-old patient who is taking Morphine via a patient-controlled analgesia (PCA) following surgery. The nurse finds the patient difficult to arouse and his respirations are 6 per minute. The most appropriate action by the nurse is to administer?

CRE training predominantly uses the aerobic/oxidative system to supply energy to the body. 

A person falls from the top of a tall building.  To save the person, Spiderman launches himself downward, from the top of the building,  toward the person, 2.5 s later with a speed 30.0 m/s.  How long will it take Spiderman to catch up to the falling person after he launches?
