Abstract
A torque bar suspension scale having a platform for supporting objects to be weighed and a pair of torque bars with each torque bar being disposed at an opposite end of the platform. Strap assemblies are connected to the platform, the torque bars and a frame whereby the torque bars are rotated in response to a weight being disposed on the platform. Each strap assembly comprises a strap having a rectangularly shaped cross section.
