A beam has dimensions of b = 16 in., h = 22 in., and d = 19.5 in. and is reinforced with 5 No. 7 bars. The concrete strength is 5,800 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.

A simply supported beam with dimensions of b = 14 in., h = 22 in., d = 19.5 in., and L = 22 ft supports a uniform service (unfactored) dead load consisting of its own weight plus 1.8 kips/ft and a uniform service (unfactored) live load of 1.4 kips/ft. The concrete is normal-weight concrete. Determine the moment due to the factored loads, Mu.      

For non-prestressed bars and wires, the modulus of elasticity of steel is assumed to be _______.

A temperature of -78.5oC corresponds to 194.65 K

A simply supported beam with dimensions of b = 10 in., h = 26 in., d = 23.5 in., and L = 21 ft supports a uniform service (unfactored) dead load consisting of its own weight plus 1.1 kips/ft and a uniform service (unfactored) live load of 1.0 kips/ft. The concrete is normal-weight concrete. Determine the moment due to the factored loads, Mu.

A beam has dimensions of b = 16 in., h = 22 in., and d = 19.5 in. and is reinforced with 4 No. 5 bars. The concrete strength is 9,400 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth to the neutral surface is c = 0.89535 in., determine the strain in the reinforcement.

A beam has dimensions of b = 14 in., h = 26 in., and d = 23.5 in. and is reinforced with 5 No. 8 bars. The concrete strength is 8,500 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the strength Mn for this beam.
