Force P = 46 N is applied to a lever at the end of a 31-mm-diameter shaft. Force Q = 835 N is applied directly to the shaft. Determine the magnitude of the shear stress τxy at point H. Let a = 135 mm and b = 230 mm.

A driver accidentally bumped a fire hydrant creating a bending moment of 765 N·m in the pipe below. The pipe has an inside diameter of 170 mm and a wall thickness of 5 mm and is pressurized to 350 kPa. Determine the largest normal stress along the length of the pipe.

For a refreshing drink on a hot day, Matt wants the Frozen Pineapple Passionfruit Lemonade of Starbucks. What type of demand does Matt have?     

A 790 N person stands at the end of a 1.38 m cantilever beam. The beam has a base of 75 mm and a height of 165 mm. Determine the maximum bending stress in the beam.

A tank with an inside diameter of 345 mm, a length of 740 mm, and a wall thickness of 4.0 mm was designed to withstand a pressure of 660 kPa. If the outside of the tank has corroded such that the thickness is now 88% of the original value, what should the pressure now be limited to?

Q19. A nurse is assessing an adolescent who has an exacerbation of Graves’ disease. Which of the following findings should the nurse expect?

A simply supported beam with dimensions of b = 14 in., h = 30 in., d = 27.5 in., and L = 16 ft supports a uniform service (unfactored) dead load of 2.1375 kips/ft including its own self weight plus a uniform service (unfactored) live load of 1.0 kips/ft. The concrete is normal-weight concrete. The beam is reinforced with 2 No. 8 bars. The concrete strength is 4,900 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the maximum applied bending moment due to the combined service loads (dead plus live), Ma.      

The spherical face shield of an astronaut’s helmet is made from polycarbonate with a yield strength of 103 MPa. The shield has an outside diameter of 365 mm and a thickness of 4.9 mm. If the shield is successfully pressure tested to 845 kPa on Earth, determine the factor of safety with respect to yielding.

Force P = 40 N is applied to a lever at the end of a 30-mm-diameter shaft. Force Q = 920 N is applied directly to the shaft. Determine the normal stress σy at point K. Let a = 170 mm and b = 240 mm.

The pressure hull of a space station module has an inside diameter of 4.6 m, a length of 5.2 m, and a wall thickness of 2.7 mm. It is made from an aluminum alloy with a yield strength of 271 MPa. If the hull is successfully pressure tested to 170 kPa on Earth, determine the factor of safety with respect to yielding.
