Unformatted text preview: machine member which is subjected to alternating direct compressive and tensile forces. Since the compressive forces are much higher than the tensile forces, therefore, the cross-section of the connecting rod is designed as a strut and the Rankine’s formula is used. A connecting rod, as shown in Fig. 32.12, subjected to an axial load W may buckle with X-axis as neutral axis (i.e. in the plane of motion of the connecting rod) or Y-axis as neutral axis (i.e. in the plane perpendicular to the plane of motion). The connecting rod is considered like both ends hinged for buckling about X-axis and both ends fixed for buckling about Y-axis. A connecting rod should be equally strong in buckling about both the axes. Let A = Cross-sectional area of the connecting rod, l = Length of the connecting rod, σc = Compressive yield stress, WB = Buckling load, Ixx and Iyy = Moment of inertia of the section about X-axis and Y -axis respectively, and kxx and kyy = Radius of gyration of the section about X -axis and Y - axis respectively. According to Ra...
