Question

Question 5 1 pts You have modellied a cantilever beam with 2 beam elements (2D) for free vibration e to obtain analysis. How many transverse vibration mode shapes would you be abl from such FE analysis? 2 Question 6 1 pts What is the condition imposed for a rigid link between two nodes? O The displacements are constrained but the rotations are not. O The rotations are constrained but the displacements are not. The distance between the two constrained nodes must remain constant. The rigid link is able to deform according to f ku.

Answer 1

5. option 4) 4 mode shapes as 2 nodes will have for eigen values i.e 2 for each node

6. option 2) ony rotations can be constrained if required but displacements cannot be constrained. so by analysis ansys software only rotations are restricted
