Determine the epoxy modification factor, ψe, for a rectangular beam with b = 18 in. and d = 21 in., five epoxy-coated No. 6 Grade 60 tension-reinforcement bars placed in the top of the beam, and No. 3 Grade 40 stirrups located every 8 in. along the span. Assume 4,000-psi normal-weight concrete and a clear cover of 1.5 in.

A driver accidentally bumped a fire hydrant creating a bending moment of 610 N·m in the pipe below. The pipe has an inside diameter of 180 mm and a wall thickness of 6 mm and is pressurized to 330 kPa. Determine the largest normal stress along the length of the pipe.

Force P = 40 N is applied to a lever at the end of a 34-mm-diameter shaft. Force Q = 115 N is applied directly to the shaft. Determine the magnitude of the shear stress τyz at point K. Let a = 135 mm and b = 200 mm.

A tank with an inside diameter of 345 mm, a length of 690 mm, and a wall thickness of 3.3 mm was designed to withstand a pressure of 725 kPa. If the outside of the tank has corroded such that the thickness is now 95% of the original value, what should the pressure now be limited to?

LIMB REATTACHMENT- O.R. room temperature should be warmed to ___________ degrees to prevent vasoconstriction of the extremities.

The pressure hull of a space station module has an inside diameter of 4.7 m, a length of 5.5 m, and a wall thickness of 3.0 mm. It is made from an aluminum alloy with a yield strength of 241 MPa. If the hull is successfully pressure tested to 180 kPa on Earth, determine the factor of safety with respect to yielding.
