I'm looking for a cheap valve designed to fit in a 1" diameter plastic or aluminium tube. An airflow designed to create a vacuum in a cup at one end of the pipe, and an air-moving fan is at the other end creating the pressure difference. The sorts of air velocities we are talking about are...
I have a steel shaft subjected to a maximum bending moment of M, and a torque of T. Its UTS is 430MPa, and its USS is 340. I need to find out the minimum diameter of this shaft.
Can anyone guide me through the process please?
