When faced with a situation in which an older patient with a terminal illness is in cardiac arrest, but written documentation regarding the patients wishes cannot be located, the EMT should:

The stress in the reinforcement goes to zero at a crack.

Larger diameter aggregate creates a rougher crack surface, allowing higher shear stresses to be transferred across cracks.
