answer 18.11 and 18.12
18.11 A steel ring with an outside diameter of 150 mm and an inside diameter of 100 mm is shrunk onto another steel ring with an inside diameter of 50 mm. An axial force of 56,54 kN is needed to push the rings apart. Calculate the pressure at the mating surface and the shrinkage allowance given that both rings are 20 mm thick and the coefficient of friction between the mating surfaces is 0,2. Using...

A glass tube of inside diameter 1.0 mm is dipped vertically into a container of mercury, with its lower end 1 cm below the mercury surface. a) What must be the gauge pressure of the air in the tube to blow a hemispherical bubble at its lower end? (Answer: 1400 Pa) b) To what height will mercury rise in the tube if the air pressure in the tube is 3000 Pa below atmospheric? The contact angle is 140 degrees and...

At a height h = 44.0 m above the ground a rocket is fired at an initial speed v0 = 168.0 m/s at an angle θ = 27 degrees above the horizontal. Ignore air resistance. The magnitude of the gravitational acceleration is 9.8 m/s2. Choose the RIGHT as positive x-direction. Choose UPWARD as psotitive y-direction. Keep 2 decimal places in all answers (a) Find v0x, the x component of the initial velocity (in m/s) (b) Find v0y, the y component...
