It is necessary to define the wall thickness of a new 4 mm diameter stent delivery balloon made from PET. The expanded diameter is 4 mm. We know from testing that the ultimate strength is 15,000 psi (103 MPa). The pressure necessary to expand the stent is 15 atm. Please help the designer. Convert all units to the English system of units and give answer in inches.

I need the whole solution for this question! Thanks 2.6 Calculate the safe working pressure for a 2 m diameter spherical container, with wall thickness 15 mm, if the ultimate tensile strength of its material is 420 MPa, the factor of safety is 6 and the efficiency of welded joints is 90%. 2.6 Calculate the safe working pressure for a 2 m diameter spherical container, with wall thickness 15 mm, if the ultimate tensile strength of its material is 420...
air under a pressure to 16 MPa. The tank has a 180 mm inner diameter and a 12 mm wall thickness (40 points) A torque of magnitude T-24kN-m is applied to the end of a tank containing 3. Part A. For a point on the outer surface of the tank, determine: a. the maximum normal stress b. the maximum shearing stress Part B. As a result of several tensile tests, it has been found that the tensile yield strength for...
A circular pipe, with an outside diameter of 30 mm and a wall thickness of 4 mm, is held stationary in a stream of air for which T-30°C, F-1 atm , and V-25 m/s . The pipe, which is made of PVC, experiences cross-flow conditions in the moving air 1) The temperature at the inner surface of the pipe is maintained at 90°C. The outer surface of the pipe is smooth. Also, assume that steady-state conditions exist. Since the outer...
