Abstract
1295343 Measuring boom bending moments electrically WARNER & SWASEY CO 4 Feb 1970 [14 Feb 1969] 22367/72 Divided out of 1295341 Heading G1N A boom assembly as disclosed in Specification 1295341 (Division G1) is described but the claims are to a self-supporting boom having a base section 16, and a plurality of additional sections 17-20 in succession outwardly from the base section, those 17, 18 being extensible, and a strain transducer Tr for sensing the bending moment on the boom and circuits operable in accordance with the respective weights and extended lengths of the sections and with the output of the sensor means to yield a plurality of signals representative of the bending moments on respective sections of the boom.
