Extract

Frame analysis problems in general involve the determination of the values of three redundancies, which can become somewhat laborious. By applying the redundancies at the elastic centre of the frame the amount of work is much reduced and the solving of simultaneous equations is avoided. The method does not seem to be very widely used and it is considered that this may be due partly to the way in which the proof has usually been presented. The following proof is given in the hope that it may assist in clarifying the method.
