10 N.A..C.A. Technical Note No. 717 … Figure 2 According to the definition of stiffness, the total moment in members "ba at joint b must be the rotation of joint b multiplied by the total stiffness of members ba. Hence, M 1 * sbc + S S 'ba 1 - r is the rotation in quarter-radians of joint b caused by the external moment M. For the…
