7.1 – ENERGY AND VIRTUAL WORK For each of the questions below, choose the correct answer True or False. NameEmail1) Energy is not conserved in non-linear systems. TRUE FALSE2) Virtual work theorem is applicable to non-linear systems. TRUE FALSE3) Virtual work theorem is applicable to non-conservative systems. TRUE FALSE4) Kinematic admissible functions must satisfy boundary conditions on forces and moments. TRUE FALSE5) Statically admissible functions satisfy equilibrium equations. TRUE FALSE6) Degree of static redundancy is zero for statically determinate structures. TRUE FALSE7) Virtual displacement must satisfy equilibrium equations. TRUE FALSE8) Virtual displacement must be kinematically admissible. TRUE FALSE9) If virtual work due to kinematically admissible displacements is zero then the displacements satisfy equilibrium. TRUE FALSE10) If virtual work due to statically admissible forces and moments is zero then displacement boundary conditions are met. TRUE FALSEDo you have any comments or suggestions?
