A 650 N person stands at the end of a 1.53 m cantilever beam. The beam has a base of 80 mm and a height of 175 mm. Determine the maximum bending stress in the beam.

Force P = 49 N is applied to a lever at the end of a 33-mm-diameter shaft. Force Q = 115 N is applied directly to the shaft. Determine the normal stress σy at point H. Let a = 140 mm and b = 200 mm.

Common medical emergencies in the pediatric population include all of the following except:

Q5. The nurse is caring for a patient who has undergone a thyroidectomy. Which patient complaint is highest priority requiring further evaluation?

A driver accidentally bumped a fire hydrant creating a bending moment of 740 N·m in the pipe below. The pipe has an inside diameter of 175 mm and a wall thickness of 9 mm and is pressurized to 305 kPa. Determine the largest normal stress along the length of the pipe.

A driver accidentally bumped a fire hydrant creating a bending moment of 770 N·m in the pipe below. The pipe has an inside diameter of 175 mm and a wall thickness of 6 mm and is pressurized to 395 kPa. Determine the largest normal stress along the length of the pipe.

A rectangular beam has a cross section of b = 18 in., h = 26 in., and d = 23.5 in. It is reinforced with three No. 6 Grade 60 bars. The concrete strength is 2,800 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the cracked moment of inertia, Icr. The neutral axis location of the cracked beam (measured from the top of the beam) is 5.0946 in.

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.

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.      

Force P = 45 N is applied to a lever at the end of a 32-mm-diameter shaft. Force Q = 125 N is applied directly to the shaft. Determine the normal stress σy at point H. Let a = 120 mm and b = 215 mm.
