An apparatus for connecting an attachment and an air beam comprising a hug strap attached to a hug strap pad, the hug strap adapted to connect with the attachment, and the hug strap pad adapted to attach to the air beam. A method of securing an attachment to an air beam comprising providing an air beam, attaching a hug strap to a hug strap pad, securing the hug strap pad (with the hug strap attached) to the air beam, and securing the attachment to the hug strap.

Method and apparatus for distributing a load about an air beam

A method and apparatus for the automatic analysis of stress in a body. The device includes a measuring head and an apparatus for traversing the measuring head across a photosensitive material attached to the body. The measuring head measures the intensity of light reflected or dispersed from the photosensitive material. The reflected or dispersed light is emitted from and received by diodes in the measuring head. Electrical signals representative of the intensity of light traversing the photosensitive material in three directions are generated for each of a set of points on the photosensitive material. The electrical signals are analyzed by computer and converted to stress and strain data which may then be displayed on a plotter or monitor. The method includes traversing the measuring head across the photosensitive material, detecting the intensity of light dispersed or reflected from the photosensitive material in three directions, analyzing the electrical signals to produce stress and strain data for the photosensitive material at each point, and displaying the resulting stress and strain data.
