A cantilever beam is subjected to following three different loading conditions: (1) a concentrated load P at its free end (Fig. a) (II) a couple Mo at its free end (Fig. b) (III) both loads acting simultaneously (Fig. c) L energy is L energy is L (c) The flexural rigidity of the beam may be assumed as EI. The strain energy due to bending when both loads act simultaneously (a) can be determined by applying the principle of superposition and the strain Mo PL ML + 6EI 2EI (b) can be determined by applying the principle of superposition and the strain Mo PL ML 6EI 2EI (c) can not be determined by applying the principle of superposition and the strain energy is PL ML M/L PML + 6EI 2EI 2EI energy is + (d) can not be determined by applying the principle of superposition and the strain ML PM L + 2EI PL ML + 6EI 2EI A cantilever beam is subjected to following three different loading conditions: (1) a concentrated load P at its free end (Fig. a) (II) a couple Mo at its free end (Fig. b) (III) both loads acting simultaneously (Fig. c) L energy is L energy is L (c) The flexural rigidity of the beam may be assumed as EI.
