1. A pin load-sensing apparatus for measuring the load between a load transferring member and load receiving members comprising an essentially cylindrical load cell integral with and surrounded by a tubular collar wherein said tubular collar comprises a plurality of cylindrical sections adapted to engage with and join said load transferring and load receiving members in pivotal coupling relationship, and wherein said essentially cylindrical load cell comprises longitudinally spaced peripheral land surfaces adapted to engage the cylindrical sections of said tubular collar, and peripheral recessed surfaces intermediate said land surfaces and positioned to concentrate axial moment stresses at the bottom peripheral portions of said recessed surfaces when a load is applied to said cell, there being a set of electrical strain gauges operationally bonded directly to the bottom peripheral portion of each of said peripheral recessed surfaces in a manner to enable said gauges to respond to differential axial moment stresses therein resulting from deformation of said load cell due to a loading force being exerted on said load cell by said load transferring member.
