What mass of copper (II) sulfate pentahydrate is needed to produce 750 g of a 12.5% M/M solution?

A beam has dimensions of b = 14 in., h = 26 in., d’ = 2.5 in., and d = 23.5 in. It is reinforced with 2 No. 5 bars on the compression side and 5 No. 8 bars on the tension side. The concrete strength is 3,100 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 6.547 in., determine the force in the compression reinforcement, Cs.

a. Plutonium-239 undergoes alpha decay to form a new element. Write the balanced equation for this process. b. Phosphorus – 32 undergoes beta decay provide the balanced chemical equation.   

In general, beams should not be less than 10 inches in width.

29. Checking clock agreement  is not important in the PET lab

A beam has dimensions of b = 16 in., h = 24 in., and d = 21.5 in. and is reinforced with 5 No. 7 bars. The concrete strength is 3,700 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth to the neutral surface is c = 4.208361 in., determine the strain in the reinforcement.

The compressive and tensile forces act through the centroid of their respective stress blocks.

The atomic number of an atom is 82 and its mass number is 207. Determine its:   1.Number of electrons 2.Number of protons 3.Number of neutrons 4.The charge of its ion

Which symbol represents the cross-sectional area of the reinforcement near the tension face of a reinforced concrete beam?

A beam has dimensions of b = 14 in., h = 24 in., and d = 21.5 in. and is reinforced with 3 No. 8 bars. The concrete strength is 8,800 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth to the neutral surface is c = 2.089087 in., determine the strain in the reinforcement.
