Thanks a bunch.
So, just to clarify, the force needed to be overcome the pressure would be related only to the area of the walls inside the cylinder in the direction of the movement.
The attached graphic will give a better idea of the exercise. So the surfaces outlined in green will be the...
I have an exercise I'm working on and had a question wiht regards to P = F/A. If I have a pump used to compress oxygen in order to increase pressure to an external cylinder, which surfaces would incur force as the piston in the pump compresses the gas?
Within the chamber holding the gas...
The mating o-rings are -001 1/2 size (.070 C.S. with .040 I.D.). The mating surface for the knob, where the o-rings make contact, has a thickness of .193" +/-.003. Essentially, the knob rests on the o-rings. For comparative purposes, if the thickness of this area was .200", a solid-on-solid...
I'm at a loss with a prototype part I'm developing which should be a relatively simple change. Basically, the proto is an offshoot of an existing part used for two years now with great success.
The part is a rotating knob with various hole sizes drilled along the inner circumference - see the...
Does the 'L' version of Zytel have any properties which increase the smoothness (or slickness) of the part. Someone at the workplace stated that he thought 'L' type materials were more often used in applications such as for bearings, etc because they exhibit less friction than the standard...
I'll be the first to admit that I am not an expert in plastics and have a question which may be simple in nature. We are re-sourcing suppliers for some knobs used on assorted products we sell. One of the knobs calls out Zytel 101 on the print. One of the potential new suppliers states that...
