10. How can photon detection be achieved in a PET/MRI scanner?

A beam has dimensions of b = 18 in., h = 26 in., and d = 23.5 in. and is reinforced with 4 No. 7 bars. The concrete strength is 3,700 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.

Three samples of sulfur were collected and their isotopes were analyzed. Below is the data for each of the isotopes. What is the average atomic mass of sulfur? Sample 1: 31.972 amu, 94.99% Sample 2: 32.971 amu, 0.75% Sample 3: 33.967 amu, 4.26%

The following table summarizes prices of various default-free zero-coupon bonds (expressed as a percentage of face value):Maturity (years)12345Price (per $100 face value)94.5289.6885.4081.6578.35The yield to maturity for the two-year zero-coupon bond is closest to ________.

If there is compressive reinforcement in a beam, you must assume in your calculations that this steel will yield.

As represents the cross sectional area of reinforcement on the tension side of the beam, and A’S represents the cross sectional area of reinforcement on the compression side of the beam.

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

If C represents the internal compressive force and T represents the internal tensile force in a singly-reinforced concrete beam that has no applied axial load, then _______.
