Abstract
Apparatus for monitoring structures and structural members for overloads has an elongated frangible closed ended tube containing a dense, visible liquid. The tube includes a central reduced cross-sectional area for forming a weak portion thereof. The tube is enclosed in a transparent shield and the tube and shield resiliently attached to the structure to be monitored. The frangible tube is designed to cause the weakened area to fracture when the tube and structure are exposed to a preselected level of an acceleration force, causing the liquid to be deposited in the shield as an indication of an overload.
