Reinforced rubber reinforcement structure are placed under angles larger than 54.7 angular degrees, the fibres want to relocate to their optimal path when pressurized. This means that the fibres will re-orient themselves until they have reached their force equilibrium. In this case this will lead to an increase in length and a decrease in diameter. With angles smaller than 54.7 degrees the opposite will occur. A product which makes use of this principle is a pneumatic muscle. For a cylinder with a constant diameter the reinforcement angle is constant as well and is 54.7º. This also known as the magic angle or
38 Degrees above a flat-line membership structure. 38 Degrees also claims its campaigns are selected by its members under its "Campaigns by You". David Babbs is Executive Director. He signs off some emails, appears in the media and frequently speaks at local 38 Degrees events. He has also represented 38 Degrees in front of parliamentary select committees. Babbs describes his motivation for campaigning as coming from "a gut feeling that things could be better, politically, socially, and environmentally and that the reason they’re not is largely due to the conscious actions of powerful people rather than due to bad luck or any
