An 80μm diameter glass fiber is confirmed to have no surface cracks longer than 5μm.  If the theoretical strength of the fiber is 5GPa, what can you predict the expected minimum breaking strength of the fiber to be?  Your answer should be in units of MPa.

Question

An 80μm diameter glass fiber is confirmed to have no surface cracks longer than 5μm.  If the theoretical strength of the fiber is 5GPa, what can you predict the expected minimum breaking strength of the fiber to be?  Your answer should be in units of MPa.

Hint:  The crack tip size will be no smaller than the ionic diameter (twice the radius) of O^2−(see appendix 2) and the crack length will be no longer than 5μm.
