A pipeline with an outside diameter of 460 mm and a wall thickness of 11 mm is pressurized to 1.6 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.

Force P = 41 N is applied to a lever at the end of a 34-mm-diameter shaft. Force Q = 925 N is applied directly to the shaft. Determine the normal stress σy at point K. Let a = 165 mm and b = 205 mm.

A simply supported beam with dimensions of b = 16 in., h = 28 in., d = 25.5 in., and L = 24 ft supports a uniform service (unfactored) dead load of 1.966667 kips/ft including its own self weight plus a uniform service (unfactored) live load of 1.3 kips/ft. The beam is reinforced with four No. 6 Grade 60 bars. The concrete strength is 8,200 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the effective moment of inertia, Ie.The cracked moment Mcr = 118.3 kip-ft, and the maximum applied bending moment due to the combined service loads (dead plus live) Ma = 235.2 kip-ft. The neutral axis location of the cracked beam (measured from the top of the beam) is 5.0301 in.

A 15-year-old female presents to the office with acne consisting of 25 comedones and 20 inflammatory lesions with no nodules. The patient can be classified as having which type of acne?

An ad agency may need to purchase photographs and illustrations from an outside supplier for its client. The agency increases the price of these advertising supplies charged to the client, at the standard rate of 17.65%. This form of compensation is known as the ____ model.        

A 505 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 160 mm. Determine the maximum bending stress in the beam.

The spherical face shield of an astronaut’s helmet is made from polycarbonate with a yield strength of 104 MPa. The shield has an outside diameter of 351 mm and a thickness of 5.4 mm. If the shield is successfully pressure tested to 920 kPa on Earth, determine the factor of safety with respect to yielding.
