Following a diagnosis of premature pubarche, which of the following signs or symptoms would be worrisome relative to the development of precocious puberty?

A beam has dimensions of b = 14 in., h = 24 in., and d = 21.5 in. and is reinforced with 3 No. 5 bars. The concrete strength is 4,600 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the strength Mn for this beam.

For the hypothetical reaction (ΔH = 215 kJ) at equilibrium                           A (g)    +    2B (aq)              6C(g)       +        D(s)             Predict whether the amount of B would increase, decrease, or remain the same for each of the following changes (1 point each)     Addition of A     Remove C     Removal of D     Increasing the pressure               Increasing the temperature      

Simply supported beams loaded with only gravity loads require longitudinal reinforcement along the top of the beam.
