A 470 N person stands in the middle of a 2.33 m simply-supported beam. The beam has a base of 90 mm and a height of 155 mm. Determine the maximum horizontal shear stress in the beam.

A pipeline with an outside diameter of 420 mm and a wall thickness of 9 mm is pressurized to 2.6 MPa. Due to thermal expansion, a compressive force of 30 kN is generated along the length of the pipes. Determine the normal stress along the length of the pipes. Ignore the bending stresses due to the weight of the pipes and the fluid that they contain.

A 810 N person stands in the middle of a 2.31 m simply-supported beam. The beam has a base of 90 mm and a height of 180 mm. Determine the maximum horizontal shear stress in the beam.

A tank with an inside diameter of 375 mm, a length of 610 mm, and a wall thickness of 3.1 mm was designed to withstand a pressure of 770 kPa. If the outside of the tank has corroded such that the thickness is now 83% of the original value, what should the pressure now be limited to?

A 475 N person stands at the end of a 1.42 m cantilever beam. The beam has a base of 95 mm and a height of 170 mm. Determine the maximum bending stress in the beam.

A driver accidentally bumped a fire hydrant creating a bending moment of 685 N·m in the pipe below. The pipe has an inside diameter of 165 mm and a wall thickness of 6 mm and is pressurized to 310 kPa. Determine the largest normal stress along the length of the pipe.

Q8.  A nurse is reviewing the medical record of a client who has been on levothyroxine for several months. Which of the following findings indicates a therapeutic response to the medication?

A pipeline with an outside diameter of 420 mm and a wall thickness of 12 mm is pressurized to 2.2 MPa. Due to thermal expansion, a compressive force of 21 kN is generated along the length of the pipes. Determine the normal stress along the length of the pipes. Ignore the bending stresses due to the weight of the pipes and the fluid that they contain.

Force P = 42 N is applied to a lever at the end of a 31-mm-diameter shaft. Force Q = 195 N is applied directly to the shaft. Determine the magnitude of the shear stress τyz at point K. Let a = 180 mm and b = 235 mm.

A tank with an inside diameter of 365 mm, a length of 930 mm, and a wall thickness of 3.6 mm was designed to withstand a pressure of 750 kPa. If the outside of the tank has corroded such that the thickness is now 90% of the original value, what should the pressure now be limited to?
