The moment-curvature relationship is linear up to the crushing point and is referred to as the cracked-elastic range.

This individual is the first in the West (per your textbook), that developed an explanation to describe how evolution might work.

A beam is singly reinforced with the reinforcement in two rows. The bottom row contains 10 No. 8 bars at a depth of 20 in. The top row contains 7 No. 5 bars at a depth of 16 in. Determine the effective (centroidal) depth, d, of the steel.

Consider Toulmin argument in relation to Paper 3, in particular the outline you submitted in the previous module. State your likely Claim, plus at least one example of Grounds. (1 point) What is a possible Rebuttal to this Claim? (1 point) With this Rebuttal in mind, revise the Claim so that it is Qualified in some way. (1 point)

A beam has dimensions of b = 14 in., h = 26 in., and d = 23.5 in. and is reinforced with 5 No. 7 bars. The concrete strength is 4,600 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth to the neutral surface is c = 4.010088 in., determine the strain in the reinforcement.

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 4 No. 8 bars on the tension side. The concrete strength is 3,700 psi, and the yield strength of the reinforcement is 60,000 psi. For the results given below, determine the strength Mn for this beam.a = 3.809 in. (depth of concrete stress block)Cc = 165.8 kips (compressive force in concrete)Cs = 23.8 kips (compressive force in steel)T = 189.6 kips (tensile force in steel)

Adjacent span loading is the common loading pattern for determining maximum shear at the supports between the loaded spans due to dead load.

Locate atom “a)” in the Atomic mass table at the bottom of the page.  Calculate the nuclear binding energy (in J/atom) for atom a). Answer format:   The answer will be in the form:  ___ x 10-12 J.  Only type the part that goes in the blank. Do not type “x 10-10 J”.  Round to 2 sig figs, do not round until the end of the calculation.

A concrete cover of at least two bar diameters is required to sufficiently bond the reinforcement to the concrete.

A full structural analysis of continuous beams and one-way slabs is often required to find the design moments and shears at critical sections (commonly midspan and faces of supports).
