Virtual work theorem is applicable to non-linear systems. TRUE FALSE 3. Virtual work theorem is applicable to non-conservative systems. TRUE FALSE 4. Kinematic admissible functions must satisfy boundary conditions on forces and moments. TRUE FALSE 5. Statically admissible functions satisfy equilibrium equations. TRUE FALSE 6. Degree of static redundancy is zero for statically determinate structures. TRUE FALSE 7. Virtual displacement must satisfy equilibrium equations. TRUE FALSE 8. Virtual displacement must be kinematically admissible. TRUE FALSE 9. If virtual work due to kinematically admissible displacements is zero then the displacements satisfy equilibrium. TRUE FALSE 10.
