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
Allied Masonic Degrees equivalent of the Allied Masonic Degrees, nor are the degrees for which it is responsible carried out under the auspices of any of the Scottish masonic bodies, although the 'Red Cross of Babylon' is a truncated version of the Scottish 'Babylonish Pass' degree under the control of the Supreme Grand Royal Arch Chapter of Scotland. There is no reciprocal agreement on intervisitation in the 'Lodge & Council' degrees between the Supreme Grand Royal Arch Chapter of Scotland and the Council of the Allied Masonic Degrees. Nonetheless, "The Grand Council of the Allied Masonic Degrees of England and Wales and Districts
