I'm brainstorming different potential layouts to lift a load from the ground to a platform (see attached). In this particular layout, the mechanism would see more than 180 degrees of articulation and as a result the four-bar linkage becomes unstable when the four pivot axes become coplanar...
I'm working on an application that utilizes liquified CO2 (at vapor pressure) to act on a hydraulic bladder (similar to an accumulator) with the goal of providing a constant pressure as the volume of oil in the bladder fluctuates. The device operates in a 17-26C environment creating fluctuation...
Hello,
I'm considering using Cellophane in an application to reduce CO2 permeability in a pressurized container. Can anyone tell me if cellophane can be formed into any shapes other than film? I.E. can it be used as a coating, extruded, injection molded, etc?
Thanks for your time!
Hi,
I'm working on a medical design project that will utilize a high pressure gas (likely CO2) stored at the vapor pressure (~850 psi) over a long period of time (2-4 years). My concern is gas permeation of the CO2 over time. The "pressure vessel" will likely be injection molded out of ABS...
Hi,
I'm trying to determine the proper equation required to calculate volumetric ratios between compressed, liquified gases and the same gas at atmospheric pressure. For example, let's assume that I have 10cc of liquified CO2 in a pressure vessel at room temperature ( Vapor pressure = 849 psig...
Hi,
I'm looking for the tensile and yield strength of 6061-T6 Aluminum at 200 degrees Fahrenheit (150 and 300 as well if possible)? Also, can you reference the source of the data or the chart?
Thanks!
Matt
