A beam has dimensions of b = 16 in., h = 24 in., and d = 21.5 in. and is reinforced with 5 No. 5 bars. The concrete strength is 7,900 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the nominal moment capacity, Mn, of the beam.

Use the MWFRS Envelope Procedure in ASCE 7-10 Chapter 28, Part 1 to answer this question. Assume that the building meets the conditions described therein. You have been tasked with designing an enclosed building. The mean roof height is 25 ft, and the roof angle is 20 degrees. The basic wind speed provided by the local building authority is 135 mph. Assume that exposure category C is applicable and that the building is not located on a hill or an escarpment. Determine the velocity pressure exposure coefficient, Kh.

Determine β1 given that f’c = 10,000 psi.

A simply supported beam with dimensions of b = 10 in., h = 28 in., d = 25.5 in., and L = 19 ft supports a uniform service (unfactored) dead load consisting of its own weight plus 1.0 kips/ft and a uniform service (unfactored) live load of 0.9 kips/ft. The concrete is normal-weight concrete. Determine the moment due to the factored loads, Mu.      

A beam has dimensions of b = 18 in., h = 30 in., and d = 27.5 in. and is reinforced with 5 No. 6 bars. The concrete strength is 2,800 psi, and the yield strength of the reinforcement is 60,000 psi. Assuming the reinforcement has yielded, determine the tensile force T in the reinforcement.

An experimental test of the hypothesis to explain the origin of the first organic compounds on Earth might include all of the following sequential steps, except for

A simply supported beam with dimensions of b = 16 in., h = 24 in., d = 21.5 in., and L = 21 ft supports a uniform service (unfactored) dead load consisting of its own weight plus 1.0 kips/ft and a uniform service (unfactored) live load of 0.8 kips/ft. The concrete is normal-weight concrete. Determine the moment due to the factored loads, Mu.      

You can insert two types of graphics into a Word document: a drawing object and a picture.

A beam has dimensions of b = 16 in., h = 22 in., and d = 19.5 in. and is reinforced with 3 No. 5 bars. The concrete strength is 3,100 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the compressive stress block is a = 1.323529 in. and the strain in the reinforcement is εs = 0.03457, determine the strength φMn for this beam. Assume the transverse reinforcement is not spirals.

What force does a trampoline have to apply to a 45.0-kg gymnast to accelerate her straight up at 7.50 m/s^2 ? Note that the answer is independent of the velocity of the gymnast—she can be moving either up or down, or be stationary.
