- A rubber string of cross section A is pulled by a force P along the axis. Comment on the normal stresses developed.
- Is there a situation of loading possible for which the stress tensor matrix will cease to be symmetric?
- There is a string A'A and at A there is a mass m. From mass there is a string B'B and there is a mass m loaded at B. A force F to the mass m loaded at B. The task is to break the thread B'B. Is it possible? (A'A and B'B are strings with same properties)
