The piston diameters in fig. p1-58e are d1 = 10 cm and d2 = 4 cm. when the pressure in chamber 2 is 2000 kpa and the pressure in chamber 3 is 700 kpa, what is the pressure in chamber 1, in kpa?

Which is not true about oxygen-17 and oxygen-18?

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.
