The ThighMaster is an exercise product designed to shape one's thighs .
8-492: The device is essentially two pieces of metal tube bent in a loop and connected with a hinge . The intended use is to put the ThighMaster between the knees and squeeze them together. This exercises the hip adductors . The simple mechanism allows exercising any suitable muscle where a small angle can be created to press it, for example the biceps (elbow flexion) or the hamstrings (knee flexion). Advertisements emphasized that
16-480: A hinge, rather than a simpler device such as a slide, is to prevent the separation of adjacent components. When no bending stresses are transmitted across the hinge, it is called a zero moment hinge . A variety of self-actuating, self-locking hinges have been developed for spacecraft deployable structures such as solar array panels, synthetic aperture radar antennas, booms, radiators, etc. Deployable structure Too Many Requests If you report this error to
24-448: Is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them. Two objects connected by an ideal hinge rotate relative to each other about a fixed axis of rotation , with all other translations or rotations prevented; thus a hinge has one degree of freedom . Hinges may be made of flexible material or moving components. In biology , many joints function as hinges, such as
32-600: The OED , the English word hinge is related to hang . Other types of hinges include: Since at least medieval times, there have been hinges to draw bridges for defensive purposes for fortified buildings. Hinges are used in contemporary architecture where building settlement can be expected over the life of the building. For example, the Dakin Building in Brisbane , California ,

64-489: Was designed with its entrance ramp on a large hinge to allow settlement of the building built on piles over bay mud . This device was effective until October 2006, when it was replaced due to damage and excessive ramp slope. Hinges appear in large structures such as elevated freeway and railroad viaducts, to reduce or eliminate the transfer of bending stresses between structural components, typically in an effort to reduce sensitivity to earthquakes . The primary reason for using
