An incompressible fluid is flowing through a horizontal pipe with a constriction. The velocity of the fluid in the wide section of the pipe is 6.00 m/s and the velocity of the fluid in the narrow section of pipe is 8.00 m/s. The pressure of the fluid in the wide section is 250 kPa. What is the pressure in the narrow section of the pipe? (density of the fluid is 1000 
A. 183 kPa
B. 236 kPa
C. 268 kPa
D. 285 kPa
E. 298 kPa
B. 236 kPa

A fastener bolt for the airframe of a glider has a cross-sectional area of 1.0 square cm and a length of 4.0 cm. The part must be able withstand a tensile force of 1.0 × 104 N, and as a factor of safety this tensile force can produce a stress of no more than 50 percent of the tensile yield stress in the bolt. For damage tolerance the bolt must have at least 10 percent strain to fracture. Because weight is critical for this glider design the maximum weight possible for this bolt is 8.0 g. The bolt is not subject to high or low temperatures. Of the materials covered in this chapter what would be the best material to select? Because this is an aircraft part it not necessary to choose the cheapest material, but excessive cost should be avoided.
