Water is placed in the container shown. Itis open to the atmosphere at the top. Thediameterℓ1=0.2m, diameterℓ2=0.07 m, and height is 0.47 m. What is the gauge pressure at point A when spigot C is closed? The density of water isrho=1g/cm3andg=9.8m/s2.Atmospheri c pressure is 10100 N/m2.Theaccelerationofgravity is 9.8m/s2.Answer in units of N/m2.

Asolid round steel rod 6.25 mm in diameter and 375 mm long is rigidly bonded to the end of solid square brass rod 25 mm on a side and 300 mm long. the geometric axes of the bare are along the same line. an axial tensile force of 5.4 kn is applied at the extreme ends of the assembly. for steel e = 200 gpa and for brass e = 90 gpa. determine the total elongation for the assembly.

The average density of the planet uranus is 1.27 103 kg/m3. the ratio of the mass of neptune to that of uranus is 1.19. the ratio of the radius of neptune to that of uranus is 0.969. find the average density of neptune.
