Determine the casting-position modification factor, ψt, for a rectangular beam with b = 17 in. and d = 21 in., four uncoated No. 9 Grade 60 tension-reinforcement bars placed in the bottom of the beam, and No. 4 Grade 40 stirrups located every 12 in. along the span. Assume 8,000-psi normal-weight concrete and a clear cover of 1.75 in.

Use ACI 318-14 Table 25.4.2.2 to determine the development length for the straight tension bars (no hooks) in a rectangular beam with b = 16 in. and d = 21 in., five uncoated No. 9 Grade 60 bars placed in the bottom of the beam, and No. 4 Grade 60 stirrups located every 8 in. along the span. Assume 7,000-psi lightweight concrete and a clear cover of 1.75 in.

Determine the casting-position modification factor, ψt, for a rectangular beam with b = 16 in. and d = 21 in., four epoxy-coated No. 9 Grade 60 tension-reinforcement bars placed in the top of the beam, and No. 4 Grade 40 stirrups located every 10 in. along the span. Assume 8,000-psi lightweight concrete and a clear cover of 1.75 in.

Force P = 48 N is applied to a lever at the end of a 35-mm-diameter shaft. Force Q = 835 N is applied directly to the shaft. Determine the normal stress σy at point K. Let a = 165 mm and b = 235 mm.

Use ACI 318-14 Table 25.4.2.2 to determine the development length for the straight tension bars (no hooks) in a rectangular beam with b = 18 in. and d = 20 in., three uncoated No. 8 Grade 60 bars placed in the top of the beam, and No. 3 Grade 40 stirrups located every 10 in. along the span. Assume 8,000-psi lightweight concrete and a clear cover of 1.75 in.

Determine the epoxy modification factor, ψe, for a rectangular beam with b = 17 in. and d = 20 in., four epoxy-coated No. 9 Grade 60 tension-reinforcement bars placed in the bottom of the beam, and No. 4 Grade 40 stirrups located every 8 in. along the span. Assume 7,000-psi normal-weight concrete and a clear cover of 1.75 in.

A rectangular beam has a cross section of b = 18 in., h = 26 in., and d = 23.5 in. It is reinforced with four No. 8 Grade 60 bars. The concrete strength is 5,500 psi (normal weight). The beam has Grade 60 No. 3 stirrups satisfying ACI 318-14 Sections 9.7.6.2.2 and 9.6.3.3. Determine the strength φMn for this beam.

A 850 N person stands in the middle of a 2.38 m simply-supported beam. The beam has a base of 90 mm and a height of 175 mm. Determine the maximum horizontal shear stress in the beam.

The pressure hull of a space station module has an inside diameter of 4.4 m, a length of 5.3 m, and a wall thickness of 2.7 mm. It is made from an aluminum alloy with a yield strength of 256 MPa. If the hull is successfully pressure tested to 180 kPa on Earth, determine the factor of safety with respect to yielding.
