A 845 N person stands in the middle of a 2.63 m simply-supported beam. The beam has a base of 95 mm and a height of 150 mm. Determine the maximum horizontal shear stress in the beam.

A pipeline with an outside diameter of 490 mm and a wall thickness of 11 mm is pressurized to 1.7 MPa. Due to thermal expansion, a compressive force of 20 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.

The pressure hull of a space station module has an inside diameter of 4.6 m, a length of 5.7 m, and a wall thickness of 2.5 mm. It is made from an aluminum alloy with a yield strength of 262 MPa. If the hull is successfully pressure tested to 185 kPa on Earth, determine the factor of safety with respect to yielding.

Force P = 50 N is applied to a lever at the end of a 32-mm-diameter shaft. Force Q = 165 N is applied directly to the shaft. Determine the normal stress σy at point H. Let a = 125 mm and b = 210 mm.

A pipeline with an outside diameter of 410 mm and a wall thickness of 9 mm is pressurized to 1.7 MPa. Due to thermal expansion, a compressive force of 23 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 = 40 N is applied to a lever at the end of a 30-mm-diameter shaft. Force Q = 140 N is applied directly to the shaft. Determine the normal stress σy at point H. Let a = 155 mm and b = 230 mm.
